Struct routerify::RouterService [−][src]
pub struct RouterService<B, E> { /* fields omitted */ }
Expand description
A Service
to process incoming requests.
This RouterService<B, E>
type accepts two type parameters: B
and E
.
- The
B
represents 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,B
could be hyper::Body type. - The
E
represents any error type which will be used by route handlers and the middlewares. This error type must implement the std::error::Error.
Examples
use hyper::{Body, Request, Response, Server};
use routerify::{Router, RouterService};
use std::convert::Infallible;
use std::net::SocketAddr;
// A handler for "/" page.
async fn home(_: Request<Body>) -> Result<Response<Body>, Infallible> {
Ok(Response::new(Body::from("Home page")))
}
fn router() -> Router<Body, Infallible> {
Router::builder()
.get("/", home)
.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();
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);
}
}
