Struct rocket::Route

pub struct Route {
    pub method: Method,
    pub handler: Handler,
    pub base: URI<'static>,
    pub uri: URI<'static>,
    pub rank: isize,
    pub format: Option<MediaType>,
}

A route: a method, its handler, path, rank, and format/media type.

Fields

method: Method

The method this route matches against.

handler: Handler

The function that should be called when the route matches.

base: URI<'static>

The base mount point of this Route.

uri: URI<'static>

The uri (in Rocket format) that should be matched against. This uri already includes the base mount point.

rank: isize

The rank of this route. Lower ranks have higher priorities.

format: Option<MediaType>

The media type this route matches against, if any.

Methods

impl Route

pub fn new<S>(m: Method, path: S, handler: Handler) -> Route where     S: AsRef<str>,

Creates a new route with the given method, path, and handler with a base of /.

Ranking

The route rank's is set so that routes with static paths are ranked higher than route's with dynamic paths, and routes with query strings are ranked higher than ranks without query strings. This default ranking is summarized by the table below:

static path	query	rank
yes	yes	-4
yes	no	-3
no	yes	-2
no	no	-1

Example

use rocket::{Request, Route, Data};
use rocket::handler::Outcome;
use rocket::http::Method;

fn handler<'r>(request: &'r Request, _data: Data) -> Outcome<'r> {
    Outcome::from(request, "Hello, world!")
}

// this is a rank -3 route matching requests to `GET /`
let index = Route::new(Method::Get, "/", handler);

// this is a rank -4 route matching requests to `GET /?<name>`
let index_name = Route::new(Method::Get, "/?<name>", handler);

// this is a rank -1 route matching requests to `GET /<name>`
let name = Route::new(Method::Get, "/<name>", handler);

pub fn ranked<S>(rank: isize, m: Method, uri: S, handler: Handler) -> Route where     S: AsRef<str>,

Creates a new route with the given rank, method, path, and handler with a base of /.

Example

use rocket::{Request, Route, Data};
use rocket::handler::Outcome;
use rocket::http::Method;

fn handler<'r>(request: &'r Request, _data: Data) -> Outcome<'r> {
    Outcome::from(request, "Hello, world!")
}

// this is a rank 1 route matching requests to `GET /`
let index = Route::ranked(1, Method::Get, "/", handler);

pub fn base(&self) -> &str

Retrieves the path of the base mount point of this route as an &str.

Example

use rocket::{Request, Route, Data};
use rocket::handler::Outcome;
use rocket::http::Method;

fn handler<'r>(request: &'r Request, _data: Data) -> Outcome<'r> {
    Outcome::from(request, "Hello, world!")
}

let mut index = Route::ranked(1, Method::Get, "/", handler);
assert_eq!(index.base(), "/");
assert_eq!(index.base.path(), "/");

pub fn set_base<S>(&mut self, path: S) where     S: AsRef<str>,

Sets the base mount point of the route. Does not update the rank or any other parameters.

Example

use rocket::{Request, Route, Data};
use rocket::handler::Outcome;
use rocket::http::Method;

fn handler<'r>(request: &'r Request, _data: Data) -> Outcome<'r> {
    Outcome::from(request, "Hello, world!")
}

let mut index = Route::ranked(1, Method::Get, "/", handler);
assert_eq!(index.base(), "/");
assert_eq!(index.base.path(), "/");

index.set_base("/hi");
assert_eq!(index.base(), "/hi");
assert_eq!(index.base.path(), "/hi");

pub fn set_uri<S>(&mut self, uri: S) where     S: AsRef<str>,

Sets the path of the route. Does not update the rank or any other parameters.

Example

use rocket::{Request, Route, Data};
use rocket::handler::Outcome;
use rocket::http::Method;

fn handler<'r>(request: &'r Request, _data: Data) -> Outcome<'r> {
    Outcome::from(request, "Hello, world!")
}

let mut index = Route::ranked(1, Method::Get, "/", handler);
assert_eq!(index.uri.path(), "/");

index.set_uri("/hello");
assert_eq!(index.uri.path(), "/hello");
