Struct Params

pub struct Params<'k, 'v> { /* private fields */ }

A list of parameters returned by a route match.

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

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

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

Implementations

impl<'k, 'v> Params<'k, 'v>

pub fn len(&self) -> usize

Returns the number of parameters.

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

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

pub fn iter(&self) -> ParamsIter<'_, 'k, 'v>

Returns an iterator over the parameters in the list.

pub fn is_empty(&self) -> bool

Returns true if there are no parameters in the list.

Trait Implementations

impl<'k, 'v> Clone for Params<'k, 'v>

fn clone(&self) -> Params<'k, 'v>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'k, 'v> Debug for Params<'k, 'v>

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

Formats the value using the given formatter.

impl<'k, 'v> Ord for Params<'k, 'v>

fn cmp(&self, other: &Params<'k, 'v>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'k, 'v> PartialEq for Params<'k, 'v>

fn eq(&self, other: &Params<'k, 'v>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'k, 'v> PartialOrd for Params<'k, 'v>

fn partial_cmp(&self, other: &Params<'k, 'v>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
