Struct RouteParams

Source
pub struct RouteParams(/* private fields */);
Expand description

Represents a map of the route parameters using the name of the parameter specified in the path as their respective keys.

Please refer to the Route Parameters section for more info.

Note: This type shouldn’t be created directly. It will be populated into the req object of the route handler and can be accessed as req.params().

Implementations§

Source§

impl RouteParams

Source

pub fn new() -> RouteParams

Creates an empty route parameters map.

Source

pub fn with_capacity(capacity: usize) -> RouteParams

Creates an empty route parameters map with the specified capacity.

Source

pub fn set<N: Into<String>, V: Into<String>>( &mut self, param_name: N, param_val: V, )

Sets a new parameter entry with the specified key and the value.

Source

pub fn get<N: Into<String>>(&self, param_name: N) -> Option<&String>

Returns the route parameter value mapped with the specified key.

§Examples
use routerify::{Router, RouteParams};
use routerify::ext::RequestExt;
use hyper::{Response, Body};

let router = Router::builder()
    .get("/users/:userName/books/:bookName", |req| async move {
        let params: &RouteParams = req.params();
         
        let user_name = params.get("userName").unwrap();
        let book_name = params.get("bookName").unwrap();

        Ok(Response::new(Body::from(format!("Username: {}, Book Name: {}", user_name, book_name))))
     })
     .build()
     .unwrap();
Source

pub fn has<N: Into<String>>(&self, param_name: N) -> bool

Checks if a route parameter exists.

§Examples
use routerify::{Router, RouteParams};
use routerify::ext::RequestExt;
use hyper::{Response, Body};

let router = Router::builder()
    .get("/users/:userName", |req| async move {
        let params: &RouteParams = req.params();
         
        if params.has("userName") {
            Ok(Response::new(Body::from(params.get("userName").unwrap().to_string())))
        } else {
            Ok(Response::new(Body::from("username is not provided")))
        }
     })
     .build()
     .unwrap();
Source

pub fn len(&self) -> usize

Returns the length of the route parameters.

Source

pub fn is_empty(&self) -> bool

Source

pub fn params_names(&self) -> impl Iterator<Item = &String>

Returns an Iterator over the parameter names.

Source

pub fn iter(&self) -> impl Iterator<Item = (&String, &String)>

Returns an Iterator over the parameter entries as (parameter_name: &String, parameter_value: &String).

Source

pub fn extend(&mut self, other_route_params: RouteParams)

Extends the current parameters map with other one.
