Enum routerify::Middleware [−][src]
pub enum Middleware<B, E> {
Pre(PreMiddleware<E>),
Post(PostMiddleware<B, E>),
}Expand description
Enum type for all the middleware types. Please refer to the Middleware for more info.
This Middleware<B, E> type accepts two type parameters: B and E.
- The
Brepresents the response body type which will be used by route handlers and the middlewares and this body type must implement the HttpBody trait. For an instance,Bcould be hyper::Body type. - The
Erepresents any error type which will be used by route handlers and the middlewares. This error type must implement the std::error::Error.
Variants
Pre(PreMiddleware<E>)Variant for the pre middleware. Refer to Pre Middleware for more info.
Post(PostMiddleware<B, E>)Variant for the post middleware. Refer to Post Middleware for more info.
Implementations
Creates a pre middleware with a handler at the /* path.
Examples
use routerify::{Router, Middleware}; use hyper::{Request, Body}; use std::convert::Infallible; let router = Router::builder() .middleware(Middleware::pre(|req| async move { /* Do some operations */ Ok(req) })) .build() .unwrap();
Creates a post middleware with a handler at the /* path.
Examples
use routerify::{Router, Middleware}; use hyper::{Response, Body}; use std::convert::Infallible; let router = Router::builder() .middleware(Middleware::post(|res| async move { /* Do some operations */ Ok(res) })) .build() .unwrap();
pub fn post_with_info<H, R>(handler: H) -> Middleware<B, E> where
H: Fn(Response<B>, RequestInfo) -> R + Send + Sync + 'static,
R: Future<Output = Result<Response<B>, E>> + Send + 'static,
pub fn post_with_info<H, R>(handler: H) -> Middleware<B, E> where
H: Fn(Response<B>, RequestInfo) -> R + Send + Sync + 'static,
R: Future<Output = Result<Response<B>, E>> + Send + 'static, Creates a post middleware which can access request info e.g. headers, method, uri etc. It should be used when the post middleware trandforms the response based on the request information.
Examples
use routerify::{Router, Middleware, PostMiddleware, RequestInfo}; use hyper::{Response, Body}; use std::convert::Infallible; async fn post_middleware_with_info_handler(res: Response<Body>, req_info: RequestInfo) -> Result<Response<Body>, Infallible> { let headers = req_info.headers(); // Do some response transformation based on the request headers, method etc. Ok(res) } let router = Router::builder() .middleware(Middleware::post_with_info(post_middleware_with_info_handler)) .build() .unwrap();
Create a pre middleware with a handler at the specified path.
Examples
use routerify::{Router, Middleware}; use hyper::{Request, Body}; use std::convert::Infallible; let router = Router::builder() .middleware(Middleware::pre_with_path("/my-path", |req| async move { /* Do some operations */ Ok(req) }).unwrap()) .build() .unwrap();
