Struct routerify::RouterBuilder[−][src]

pub struct RouterBuilder<B, E> { /* fields omitted */ }

Builder for the Router type.

This RouterBuilder<B, E> type accepts two type parameters: B and E.

Examples

use routerify::{Router, Middleware};
use hyper::{Response, Request, Body};

async fn home_handler(req: Request<Body>) -> Result<Response<Body>, hyper::Error> {
    Ok(Response::new(Body::from("home")))
}

async fn upload_handler(req: Request<Body>) -> Result<Response<Body>, hyper::Error> {
    Ok(Response::new(Body::from("upload")))
}

async fn some_pre_middleware_handler(req: Request<Body>) -> Result<Request<Body>, hyper::Error> {
    Ok(req)
}

// Use Router::builder() method to create a new RouterBuilder instance.
// We will use hyper::Body as response body type and hyper::Error as error type.
let router: Router<Body, hyper::Error> = Router::builder()
    .get("/", home_handler)
    .post("/upload", upload_handler)
    .middleware(Middleware::pre(some_pre_middleware_handler))
    .build()
    .unwrap();

pub fn scope<P>(self, path: P, router: Router<B, E>) -> Self where
    P: Into<String>, [src]

It mounts a router onto another router. It can be very useful when you want to write modular routing logic.

Examples

use routerify::Router;
use hyper::{Response, Request, Body};

mod api {
    use routerify::Router;
    use hyper::{Response, Request, Body};

    pub fn router() -> Router<Body, hyper::Error> {
        Router::builder()
         .get("/users", |req| async move { Ok(Response::new(Body::from("User list"))) })
         .get("/books", |req| async move { Ok(Response::new(Body::from("Book list"))) })
         .build()
         .unwrap()
    }
}

let router = Router::builder()
    // Now, mount the api router at `/api` path.
    .scope("/api", api::router())
    .build()
    .unwrap();

Now, the app can handle requests on: /api/users and /api/books paths.

impl<B: HttpBody + Send + Sync + 'static, E: Into<Box<dyn Error + Send + Sync>> + 'static> RouterBuilder<B, E>[src]

pub fn middleware(self, m: Middleware<B, E>) -> Self[src]

Adds a single middleware. A pre middleware can be created by Middleware::pre method and a post middleware can be created by Middleware::post method.

Examples

use routerify::{Router, Middleware};
use hyper::{Response, Request, Body};
use std::convert::Infallible;

let router = Router::builder()
     // Create and attach a pre middleware.
     .middleware(Middleware::pre(|req| async move { /* Do some operations */ Ok(req) }))
     // Create and attach a post middleware.
     .middleware(Middleware::post(|res| async move { /* Do some operations */ Ok(res) }))
     .build()
     .unwrap();

pub fn data<T: Send + Sync + 'static>(self, data: T) -> Self[src]

Specify app data to be shared across route handlers, middlewares and the error handler.

Please refer to the Data and State Sharing for more info.

pub fn err_handler<H, R>(self, handler: H) -> Self where
    H: Fn(RouteError) -> R + Send + Sync + 'static,
    R: Future<Output = Response<B>> + Send + 'static, [src]

Adds a handler to handle any error raised by the routes or any middlewares. Please refer to Error Handling section for more info.

pub fn err_handler_with_info<H, R>(self, handler: H) -> Self where
    H: Fn(RouteError, RequestInfo) -> R + Send + Sync + 'static,
    R: Future<Output = Response<B>> + Send + 'static, [src]

Adds a handler to handle any error raised by the routes or any middlewares.

Here, the handler also access request info e.g. headers, method, uri etc to generate response based on the request information.

Please refer to Error Handling section for more info.
