Struct Params 

pub struct Params { /* private fields */ }

A list of parameters returned by a route match.

let matched = router.at("/users/1")?;

// you can get a specific value by key
let id = matched.params.get("id");
assert_eq!(id, Some("1"));

// or iterate through the keys and values
for (key, value) in matched.params.iter() {
    println!("key: {}, value: {}", key, value);
}

Implementations

impl Params

pub fn len(&self) -> usize

Returns the number of parameters.

pub fn is_empty(&self) -> bool

Returns true if there are no parameters in the list.

pub fn get(&self, key: impl AsRef<str>) -> Option<&str>

Returns the value of the first parameter registered under the given key.

pub fn iter(&self) -> Iter<'_>

Trait Implementations

impl Clone for Params

fn clone(&self) -> Params

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Params

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Params

fn default() -> Self

Returns the “default value” for a type.

impl IntoIterator for Params

type Item = (SmallBoxedStr, SmallBoxedStr)

The type of the elements being iterated over.

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
