//! The `Routerify` provides a lightweight, idiomatic, composable and modular router implementation with middleware support for the Rust HTTP library [hyper.rs](https://hyper.rs/). //! //! There are a lot of web server frameworks for Rust applications out there and [hyper.rs](https://hyper.rs/) being comparably very fast and ready for production use //! is one of them, and it provides only low level APIs. It doesn't provide any complex routing feature. So, `Routerify` extends the [hyper.rs](https://hyper.rs/) library //! by providing that missing feature without compromising any performance. //! //! The `Routerify` offers the following features: //! //! - 📡 Allows defining complex routing logic. //! //! - 🔨 Provides middleware support. //! //! - 🌀 Supports Route Parameters. //! //! - 🚀 Fast as it's using [`RegexSet`](https://docs.rs/regex/1.3.7/regex/struct.RegexSet.html) to match routes. //! //! - 🍺 It supports any response body type as long as it implements the [HttpBody](https://docs.rs/hyper/0.13.5/hyper/body/trait.HttpBody.html) trait. //! //! - ❗ Provides a flexible [error handling](./index.html#error-handling) strategy. //! //! - 💁 Provides `WebSocket` [support](https://github.com/routerify/routerify-websocket) out of the box. //! //! - 🔥 Allows data/state sharing across the route and middleware handlers. //! //! - 🍗 Exhaustive [examples](https://github.com/routerify/routerify/tree/master/examples) and well documented. //! //! To generate a quick server app using [Routerify](https://github.com/routerify/routerify) and [hyper.rs](https://hyper.rs/), //! please check out [hyper-routerify-server-template](https://github.com/routerify/hyper-routerify-server-template). //! //! ## Benchmarks //! //! | Framework | Language | Requests/sec | //! |----------------|-------------|--------------| //! | [hyper v0.13](https://github.com/hyperium/hyper) | Rust 1.43.0 | 112,557 | //! | [routerify v1.1](https://github.com/routerify/routerify) with [hyper v0.13](https://github.com/hyperium/hyper) | Rust 1.43.0 | 112,320 | //! | [gotham v0.4.0](https://github.com/gotham-rs/gotham) | Rust 1.43.0 | 100,097 | //! | [actix-web v2](https://github.com/actix/actix-web) | Rust 1.43.0 | 96,397 | //! | [warp v0.2](https://github.com/seanmonstar/warp) | Rust 1.43.0 | 81,912 | //! | [go-httprouter, branch master](https://github.com/julienschmidt/httprouter) | Go 1.13.7 | 74,958 | //! | [Rocket, branch async](https://github.com/SergioBenitez/Rocket) | Rust 1.43.0 | 2,041 ? | //! //! For more info, please visit [Benchmarks](https://github.com/routerify/routerify-benchmark). //! //! ## Basic Example //! //! A simple example using `Routerify` with [hyper.rs](https://hyper.rs/) would look like the following: //! //! ```no_run //! use hyper::{Body, Request, Response, Server, StatusCode}; //! // Import the routerify prelude traits. //! use routerify::prelude::*; //! use routerify::{Middleware, Router, RouterService, RequestInfo}; //! use std::{convert::Infallible, net::SocketAddr}; //! //! // Define an app state to share it across the route handlers and middlewares. //! struct State(u64); //! //! // A handler for "/" page. //! async fn home_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> { //! // Access the app state. //! let state = req.data::<State>().unwrap(); //! println!("State value: {}", state.0); //! //! Ok(Response::new(Body::from("Home page"))) //! } //! //! // A handler for "/users/:userId" page. //! async fn user_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> { //! let user_id = req.param("userId").unwrap(); //! Ok(Response::new(Body::from(format!("Hello {}", user_id)))) //! } //! //! // A middleware which logs an http request. //! async fn logger(req: Request<Body>) -> Result<Request<Body>, Infallible> { //! println!("{} {} {}", req.remote_addr(), req.method(), req.uri().path()); //! Ok(req) //! } //! //! // Define an error handler function which will accept the `routerify::Error` //! // and the request information and generates an appropriate response. //! async fn error_handler(err: routerify::Error, _: RequestInfo) -> Response<Body> { //! eprintln!("{}", err); //! Response::builder() //! .status(StatusCode::INTERNAL_SERVER_ERROR) //! .body(Body::from(format!("Something went wrong: {}", err))) //! .unwrap() //! } //! //! // Create a `Router<Body, Infallible>` for response body type `hyper::Body` //! // and for handler error type `Infallible`. //! fn router() -> Router<Body, Infallible> { //! // Create a router and specify the logger middleware and the handlers. //! // Here, "Middleware::pre" means we're adding a pre middleware which will be executed //! // before any route handlers. //! Router::builder() //! // Specify the state data which will be available to every route handlers, //! // error handler and middlewares. //! .data(State(100)) //! .middleware(Middleware::pre(logger)) //! .get("/", home_handler) //! .get("/users/:userId", user_handler) //! .err_handler_with_info(error_handler) //! .build() //! .unwrap() //! } //! //! #[tokio::main] //! async fn main() { //! let router = router(); //! //! // Create a Service from the router above to handle incoming requests. //! let service = RouterService::new(router).unwrap(); //! //! // The address on which the server will be listening. //! let addr = SocketAddr::from(([127, 0, 0, 1], 3000)); //! //! // Create a server by passing the created service to `.serve` method. //! let server = Server::bind(&addr).serve(service); //! //! println!("App is running on: {}", addr); //! if let Err(err) = server.await { //! eprintln!("Server error: {}", err); //! } //! } //! ``` //! //! ## Routing //! //! ### Route Handlers //! //! A handler could be a function or a closure to handle a request at a specified route path. //! //! Here is a handler with a function: //! //! ``` //! use routerify::Router; //! use hyper::{Response, Request, Body}; //! use std::convert::Infallible; //! //! // A handler for "/about" page. //! async fn about_handler(_: Request<Body>) -> Result<Response<Body>, Infallible> { //! Ok(Response::new(Body::from("About page"))) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/about", about_handler) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! Here is a handler with closure function: //! //! ``` //! use routerify::Router; //! use hyper::{Response, Body}; //! # use std::convert::Infallible; //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/about", |req| async move { Ok(Response::new(Body::from("About page"))) }) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### Route Paths //! //! Route paths, in combination with a request method, define the endpoints at which requests can be made. //! Route paths can be strings or strings with glob pattern `*`. //! //! //! Here are some examples: //! //! This route path will match with exactly "/about": //! //! ``` //! use routerify::Router; //! use hyper::{Response, Body}; //! # use std::convert::Infallible; //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/about", |req| async move { Ok(Response::new(Body::from("About page"))) }) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! A route path using the glob `*` pattern: //! //! ``` //! use routerify::Router; //! use hyper::{Response, Body}; //! # use std::convert::Infallible; //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/users/*", |req| async move { Ok(Response::new(Body::from("It will match /users/, /users/any_path"))) }) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! #### Handle 404 Pages //! //! Here is an example to handle 404 pages. //! //! ``` //! use routerify::Router; //! use hyper::{Response, Body, StatusCode}; //! # use std::convert::Infallible; //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/users", |req| async move { Ok(Response::new(Body::from("User List"))) }) //! // It fallbacks to the following route for any non-existent routes. //! .any(|_req| async move { //! Ok( //! Response::builder() //! .status(StatusCode::NOT_FOUND) //! .body(Body::from("NOT FOUND")) //! .unwrap() //! ) //! }) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### Route Parameters //! //! Route parameters are named URL segments that are used to capture the values specified at their position in the URL. //! The captured values can be accessed by `req.params` and `re.param` methods using the name of the route parameter specified in the path. //! //! ```txt //! Route path: /users/:userName/books/:bookName //! Request URL: http://localhost:3000/users/alice/books/HarryPotter //! req.params() returns a hashmap: { "userName": "alice", "bookName": "HarryPotter" } //! ``` //! //! To define routes with route parameters, simply specify the route parameters in the path of the route as shown below. //! //! ``` //! use routerify::Router; //! // Add routerify prelude traits. //! use routerify::prelude::*; //! use hyper::{Response, Body}; //! # use std::convert::Infallible; //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .get("/users/:userName/books/:bookName", |req| async move { //! let user_name = req.param("userName").unwrap(); //! let book_name = req.param("bookName").unwrap(); //! //! Ok(Response::new(Body::from(format!("Username: {}, Book Name: {}", user_name, book_name)))) //! }) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### Scoping/Mounting Router //! //! The `routerify::Router` is a modular, lightweight and mountable router component. A router can be scoped in or mount to a //! different router. //! //! Here is a simple example which creates a Router and it mounts that router at `/api` path with `.scope()` method: //! //! ``` //! use routerify::Router; //! use routerify::prelude::*; //! use hyper::{Response, Body}; //! use std::convert::Infallible; //! //! fn api_router() -> Router<Body, Infallible> { //! Router::builder() //! .get("/books", |req| async move { Ok(Response::new(Body::from("List of books"))) }) //! .get("/books/:bookId", |req| async move { //! Ok(Response::new(Body::from(format!("Show book: {}", req.param("bookId").unwrap())))) //! }) //! .build() //! .unwrap() //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! // Mounts the API router at "/api" path . //! .scope("/api", api_router()) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! Now, the app can handle requests to `/api/books` as well as to `/api/books/:bookId`. //! //! ## Middleware //! //! The `Routerify` also supports Middleware functionality. If you are unfamiliar with Middleware, in short, here a middlewar is a function (or could be a closure //! function) which access the `req` and `res` object and does some changes to them and passes the transformed request and response object to the other middlewares and the actual route handler //! to process it. //! //! A Middleware function can do the following tasks: //! //! - Execute any code. //! - Transform the request and the response object. //! //! Here, the `Routerify` categorizes the middlewares into two different types: //! //! ### Pre Middleware //! //! The pre Middlewares will be executed before any route handlers and it will access the `req` object and it can also do some changes to the request object //! if required. //! //! Here is an example of a pre middleware: //! //! ``` //! use routerify::{Router, Middleware}; //! use hyper::{Request, Body}; //! use std::convert::Infallible; //! //! // The handler for a pre middleware. //! // It accepts a `req` and it transforms the `req` and passes it to the next middlewares. //! async fn my_pre_middleware_handler(req: Request<Body>) -> Result<Request<Body>, Infallible> { //! // Do some changes if required. //! let transformed_req = req; //! //! // Then return the transformed request object to be consumed by the other middlewares //! // and the route handlers. //! Ok(transformed_req) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! // Create a pre middleware instance by `Middleware::pre` method //! // and attach it. //! .middleware(Middleware::pre(my_pre_middleware_handler)) //! // A middleware can also be attached on a specific path as shown below. //! .middleware(Middleware::pre_with_path("/my-path/log", my_pre_middleware_handler).unwrap()) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! Here is a pre middleware which logs the incoming requests: //! //! ``` //! use routerify::{Router, Middleware}; //! use routerify::prelude::*; //! use hyper::{Request, Body}; //! use std::convert::Infallible; //! //! async fn logger_middleware_handler(req: Request<Body>) -> Result<Request<Body>, Infallible> { //! println!("{} {} {}", req.remote_addr(), req.method(), req.uri().path()); //! Ok(req) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .middleware(Middleware::pre(logger_middleware_handler)) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### Post Middleware //! //! The post Middlewares will be executed after all the route handlers process the request and generates a response and it will access that response object and the request info(optional) //! and it can also do some changes to the response if required. //! //! Here is an example of a post middleware: //! //! ``` //! use routerify::{Router, Middleware}; //! use hyper::{Response, Body}; //! use std::convert::Infallible; //! //! // The handler for a post middleware. //! // It accepts a `res` and it transforms the `res` and passes it to the next middlewares. //! async fn my_post_middleware_handler(res: Response<Body>) -> Result<Response<Body>, Infallible> { //! // Do some changes if required. //! let transformed_res = res; //! //! // Then return the transformed response object to be consumed by the other middlewares. //! Ok(transformed_res) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! // Create a post middleware instance by `Middleware::post` method //! // and attach it. //! .middleware(Middleware::post(my_post_middleware_handler)) //! // A middleware can also be attached on a specific path as shown below. //! .middleware(Middleware::post_with_path("/my-path/log", my_post_middleware_handler).unwrap()) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! Here is a post middleware which adds a header to the response object: //! //! ``` //! use routerify::{Router, Middleware}; //! use routerify::prelude::*; //! use hyper::{Response, Body, header::HeaderValue}; //! use std::convert::Infallible; //! //! async fn my_post_middleware_handler(mut res: Response<Body>) -> Result<Response<Body>, Infallible> { //! // Add a header to response object. //! res.headers_mut().insert("x-my-custom-header", HeaderValue::from_static("my-value")); //! //! Ok(res) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! .middleware(Middleware::post(my_post_middleware_handler)) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! #### Post Middleware with Request Info //! //! Sometimes, the post middleware requires the request informations e.g. headers, method, uri etc to generate a new response. As an example, it could be used to manage //! sessions. To register this kind of post middleware, you have to use [`Middleware::post_with_info`](./enum.Middleware.html#method.post_with_info) method as follows: //! //! ``` //! use routerify::{Router, Middleware, RequestInfo}; //! use hyper::{Response, Body}; //! use std::convert::Infallible; //! //! // The handler for a post middleware which requires request info. //! // It accepts `res` and `req_info` and it transforms the `res` and passes it to the next middlewares. //! async fn post_middleware_with_info_handler(res: Response<Body>, req_info: RequestInfo) -> Result<Response<Body>, Infallible> { //! let transformed_res = res; //! //! // Do some response transformation based on the request headers, method etc. //! let _headers = req_info.headers(); //! //! // Then return the transformed response object to be consumed by the other middlewares. //! Ok(transformed_res) //! } //! //! # fn run() -> Router<Body, Infallible> { //! let router = Router::builder() //! // Create a post middleware instance by `Middleware::post_with_info` method //! // and attach it. //! .middleware(Middleware::post_with_info(post_middleware_with_info_handler)) //! // This middleware can also be attached on a specific path as shown below. //! .middleware(Middleware::post_with_info_with_path("/my-path", post_middleware_with_info_handler).unwrap()) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### The built-in Middlewars //! //! Here is a list of some middlewares which are published in different crates: //! //! - [routerify-cors](https://github.com/routerify/routerify-cors): A post middleware which enables `CORS` to the routes. //! - [routerify-query](https://github.com/routerify/routerify-query): A pre middleware which parses the request query string. //! //! ## Data and State Sharing //! //! The `Routerify` also allows you to share data or app state across the route handlers, middlewares and the error handler via the [`RouterBuilder`](./struct.RouterBuilder.html) method //! [`data`](./struct.RouterBuilder.html#method.data). As it provides composable router API, it also allows to have app state/data per each sub-router. //! //! Here is an example to share app state: //! //! ``` //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! // Import the routerify prelude traits. //! use routerify::prelude::*; //! use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use std::{convert::Infallible, net::SocketAddr}; //! //! // Define an app state to share it across the route handlers, middlewares //! // and the error handler. //! struct State(u64); //! //! // A handler for "/" page. //! async fn home_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> { //! // Access the app state. //! let state = req.data::<State>().unwrap(); //! println!("State value: {}", state.0); //! //! Ok(Response::new(Body::from("Home page"))) //! } //! //! // A middleware which logs an http request. //! async fn logger(req: Request<Body>) -> Result<Request<Body>, Infallible> { //! // You can also access the same state from middleware. //! let state = req.data::<State>().unwrap(); //! println!("State value: {}", state.0); //! //! println!("{} {} {}", req.remote_addr(), req.method(), req.uri().path()); //! Ok(req) //! } //! //! // Define an error handler function which will accept the `routerify::Error` //! // and the request information and generates an appropriate response. //! async fn error_handler(err: routerify::Error, req_info: RequestInfo) -> Response<Body> { //! // You can also access the same state from error handler. //! let state = req_info.data::<State>().unwrap(); //! println!("State value: {}", state.0); //! //! eprintln!("{}", err); //! Response::builder() //! .status(StatusCode::INTERNAL_SERVER_ERROR) //! .body(Body::from(format!("Something went wrong: {}", err))) //! .unwrap() //! } //! //! // Create a `Router<Body, Infallible>` for response body type `hyper::Body` //! // and for handler error type `Infallible`. //! fn router() -> Router<Body, Infallible> { //! Router::builder() //! // Specify the state data which will be available to every route handlers, //! // error handler and middlewares. //! .data(State(100)) //! .middleware(Middleware::pre(logger)) //! .get("/", home_handler) //! .err_handler_with_info(error_handler) //! .build() //! .unwrap() //! } //! //! # #[tokio::main] //! # async fn run() { //! # let router = router(); //! # //! # // Create a Service from the router above to handle incoming requests. //! # let service = RouterService::new(router).unwrap(); //! # //! # // The address on which the server will be listening. //! # let addr = SocketAddr::from(([127, 0, 0, 1], 3000)); //! # //! # // Create a server by passing the created service to `.serve` method. //! # let server = Server::bind(&addr).serve(service); //! # //! # println!("App is running on: {}", addr); //! # if let Err(err) = server.await { //! # eprintln!("Server error: {}", err); //! # } //! # } //! ``` //! //! Here is an example to `mutate` app state: //! //! ``` //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! // Import the routerify prelude traits. //! use routerify::prelude::*; //! use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use std::{convert::Infallible, net::SocketAddr}; //! use std::sync::Mutex; //! //! // Define an app state to share it across the route handlers, middlewares //! // and the error handler. //! struct State(u64); //! //! // A handler for "/" page. //! async fn home_handler(req: Request<Body>) -> Result<Response<Body>, Infallible> { //! // Access the app state. //! let state = req.data::<Mutex<State>>().unwrap(); //! let mut lock = state.lock().unwrap(); //! // Mutate the app state if needed. //! lock.0 += 1; //! //! println!("Updated State value: {}", lock.0); //! //! Ok(Response::new(Body::from("Home page"))) //! } //! //! // Create a `Router<Body, Infallible>` for response body type `hyper::Body` //! // and for handler error type `Infallible`. //! fn router() -> Router<Body, Infallible> { //! Router::builder() //! // Specify the state data which will be available to every route handlers, //! // error handler and middlewares. //! .data(Mutex::new(State(100))) //! .get("/", home_handler) //! .build() //! .unwrap() //! } //! //! # #[tokio::main] //! # async fn run() { //! # let router = router(); //! # //! # // Create a Service from the router above to handle incoming requests. //! # let service = RouterService::new(router).unwrap(); //! # //! # // The address on which the server will be listening. //! # let addr = SocketAddr::from(([127, 0, 0, 1], 3000)); //! # //! # // Create a server by passing the created service to `.serve` method. //! # let server = Server::bind(&addr).serve(service); //! # //! # println!("App is running on: {}", addr); //! # if let Err(err) = server.await { //! # eprintln!("Server error: {}", err); //! # } //! # } //! ``` //! //! Here is any example on having app state per each sub-router: //! //! ``` //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! # // Import the routerify prelude traits. //! # use routerify::prelude::*; //! # use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use std::{convert::Infallible, net::SocketAddr}; //! //! mod foo { //! # use std::{convert::Infallible, net::SocketAddr}; //! # use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! pub fn router() -> Router<Body, Infallible> { //! Router::builder() //! // Specify data for this sub-router only. //! .data("Data for foo router") //! .build() //! .unwrap() //! } //! } //! //! mod bar { //! # use std::{convert::Infallible, net::SocketAddr}; //! # use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! pub fn router() -> Router<Body, Infallible> { //! Router::builder() //! // Specify data for this sub-router only. //! .data("Data for bar router") //! .build() //! .unwrap() //! } //! } //! //! fn router() -> Router<Body, Infallible> { //! Router::builder() //! // This data will be available to all the child sub-routers. //! .data(100_u32) //! .scope("/foo", foo::router()) //! .scope("/bar", bar::router()) //! .build() //! .unwrap() //! } //! ``` //! //! You can also share multiple data as follows: //! //! ``` //! # use hyper::{Body, Request, Response, Server, StatusCode}; //! # // Import the routerify prelude traits. //! # use routerify::prelude::*; //! # use routerify::{Middleware, Router, RouterService, RequestInfo}; //! # use std::{convert::Infallible, net::SocketAddr}; //! # use std::sync::Mutex; //! fn router() -> Router<Body, Infallible> { //! Router::builder() //! // Share multiple data, a single data for each data type. //! .data(100_u32) //! .data(String::from("Hello world")) //! .build() //! .unwrap() //! } //! ``` //! //! ## Error Handling //! //! Any route or middleware could go wrong and throws an error. The `Routerify` tries to add a default error handler in some cases. But, it also //! allow to attach a custom error handler. The error handler generates a response based on the error and the request info(optional). //! //! Here is an basic example: //! //! ``` //! use routerify::{Router, Middleware}; //! use routerify::prelude::*; //! use hyper::{Response, Body, StatusCode}; //! //! // The error handler will accept the thrown error in routerify::Error type and //! // it will have to generate a response based on the error. //! async fn error_handler(err: routerify::Error) -> Response<Body> { //! Response::builder() //! .status(StatusCode::INTERNAL_SERVER_ERROR) //! .body(Body::from("Something went wrong")) //! .unwrap() //! } //! //! # fn run() -> Router<Body, hyper::Error> { //! let router = Router::builder() //! .get("/users", |req| async move { Ok(Response::new(Body::from("It might raise an error"))) }) //! // Here attach the custom error handler defined above. //! .err_handler(error_handler) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` //! //! ### Error Handling with Request Info //! //! Sometimes, it's needed to to generate response on error based on the request headers, method, uri etc. The `Routerify` also provides a method [`err_handler_with_info`](./struct.RouterBuilder.html#method.err_handler_with_info) //! to register this kind of error handler as follows: //! //! ``` //! use routerify::{Router, Middleware, RequestInfo}; //! use routerify::prelude::*; //! use hyper::{Response, Body, StatusCode}; //! //! // The error handler will accept the thrown error and the request info and //! // it will generate a response. //! async fn error_handler(err: routerify::Error, req_info: RequestInfo) -> Response<Body> { //! // Now generate response based on the `err` and the `req_info`. //! Response::builder() //! .status(StatusCode::INTERNAL_SERVER_ERROR) //! .body(Body::from("Something went wrong")) //! .unwrap() //! } //! //! # fn run() -> Router<Body, hyper::Error> { //! let router = Router::builder() //! .get("/users", |req| async move { Ok(Response::new(Body::from("It might raise an error"))) }) //! // Now register this error handler. //! .err_handler_with_info(error_handler) //! .build() //! .unwrap(); //! # router //! # } //! # run(); //! ``` pub use self::error::Error; pub use self::middleware::{Middleware, PostMiddleware, PreMiddleware}; pub use self::route::Route; pub use self::router::{Router, RouterBuilder}; #[doc(hidden)] pub use self::service::RequestService; pub use self::service::RouterService; pub use self::types::{RequestInfo, RouteParams}; mod constants; mod data_map; mod error; pub mod ext; mod helpers; mod middleware; pub mod prelude; mod regex_generator; mod route; mod router; mod service; mod types; /// A Result type often returned from methods that can have routerify errors. pub type Result<T> = std::result::Result<T, Error>;
