Struct matchit::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.

const 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.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

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

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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