Expand description

Defines functions used by a builder to determine which request paths will be dispatched to a route. This trait is implemented by the top-level RouterBuilder, and also the ScopedBuilder created by DrawRoutes::scope.

Provided methods

Creates a route which matches GET and HEAD requests to the given path.

Examples
build_simple_router(|route| {
    route.get_or_head("/request/path").to(my_handler);
})

Creates a route which matches only GET requests to the given path (ignoring HEAD requests).

Examples
build_simple_router(|route| {
    route.get("/request/path").to(my_handler);
})

Creates a route which matches HEAD requests to the given path.

Examples
build_simple_router(|route| {
    route.head("/request/path").to(my_handler);
})

Creates a route which matches POST requests to the given path.

Examples
build_simple_router(|route| {
    route.post("/request/path").to(my_handler);
})

Creates a route which matches PUT requests to the given path.

Examples
build_simple_router(|route| {
    route.put("/request/path").to(my_handler);
})

Creates a route which matches PATCH requests to the given path.

Examples
build_simple_router(|route| {
    route.patch("/request/path").to(my_handler);
})

Creates a route which matches DELETE requests to the given path.

Examples
build_simple_router(|route| {
    route.delete("/request/path").to(my_handler);
})

Creates a route which matches OPTIONS requests to the given path.

Examples
build_simple_router(|route| {
    route.options("/request/path").to(my_handler);
})

Creates a single route which matches any requests to the given path with one of the given methods. The path can consist of static or dynamic segments, for example:

  • "/hello/world" - a static path, matching only a request for exactly "/hello/world"
  • "/hello/:name" - a dynamic path, matching requests for "/hello/any_value_here"
Examples
build_simple_router(|route| {
    route.request(vec![Method::GET, Method::HEAD], "/request/path").to(my_handler);
})
build_simple_router(|route| {
    // All we match on is the Accept header, the method is not considered.
    let matcher = AcceptHeaderRouteMatcher::new(vec![mime::APPLICATION_JSON]);
    route.request(matcher, "/request/path").to(my_handler);
})

Begins defining a new scope, based on a given path prefix.

Examples

build_simple_router(|route| {
    route.scope("/api", |route| {
        // Match requests to `/api/list`
        route.get("/list").to(api::list);
    });
})

Begins a new scope at the current location, with an alternate pipeline chain.

Examples
let pipelines = new_pipeline_set();
let (pipelines, default) = pipelines.add(
    new_pipeline()
        .add(NewSessionMiddleware::default().with_session_type::<Session>())
        .build()
);
let (pipelines, extended) = pipelines.add(
    new_pipeline()
        .add(NewSessionMiddleware::default().with_session_type::<AdminSession>())
        .build()
);
let pipeline_set = finalize_pipeline_set(pipelines);

let default_chain = (default, ());
let extended_chain = (extended, default_chain);

build_router(default_chain, pipeline_set, |route| {
    // Requests for the root handler use an empty set of pipelines, skipping the session
    // middlewares.
    route.with_pipeline_chain((), |route| {
        route.get("/").to(handler);
    });

    // Requests dispatched to the resource module will only invoke one session
    // middleware which is the default behavior.
    route.get("/resource/list").to(resource::list);

    // Requests for the admin handler will additionally invoke the admin session
    // middleware.
    route.with_pipeline_chain(extended_chain, |route| {
        route.get("/admin").to(admin::handler);
    });
})

Begins delegating a subpath of the tree.

Examples
fn admin_router() -> Router {
    // Implementation elided
}

build_simple_router(|route| {
    route.delegate("/admin").to_router(admin_router());
})

Begins delegating a subpath of the tree, but does not dispatch the requests via this router’s PipelineChain.

Examples
// API routes which don't require sessions.
fn api_router() -> Router {
    // Implementation elided
}

let (chain, pipelines) = single_pipeline(
    new_pipeline()
        .add(NewSessionMiddleware::default().with_session_type::<Session>())
        .build()
);

build_router(chain, pipelines, |route| {
    // Requests dispatched to the `/api` router will not invoke the session middleware.
    route.delegate_without_pipelines("/api").to_router(api_router());

    // Other requests will invoke the session middleware as normal.
    route.get("/").to(handler);
})

Begins associating routes with a fixed path in the tree. In this way, multiple routes can be quickly associated with a single location.

Examples
mod resource {
    pub fn show(state: State) -> (State, Response<Body>) {
        // Implementation elided.
    }

    pub fn update(state: State) -> (State, Response<Body>) {
        // Implementation elided.
    }

    pub fn delete(state: State) -> (State, Response<Body>) {
        // Implementation elided.
    }
}

build_simple_router(|route| {
    route.associate("/resource", |assoc| {
        assoc.get_or_head().to(resource::show);
        assoc.patch().to(resource::update);
        assoc.delete().to(resource::delete);
    });
})
