Struct ParamsMap 

pub struct ParamsMap(/* private fields */);

A key-value map of the current named route params and their values.

Implementations

impl ParamsMap

pub fn new() -> Self

Creates an empty map.

pub fn with_capacity(capacity: usize) -> Self

Creates an empty map with the given capacity.

pub fn insert(&mut self, key: impl Into<Cow<'static, str>>, value: String)

Inserts a value into the map.

If a value with that key already exists, the new value will be added to it. To replace the value instead, see replace.

pub fn replace(&mut self, key: impl Into<Cow<'static, str>>, value: String)

Inserts a value into the map, replacing any existing value for that key.

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

Gets the most-recently-added value of this param from the map.

pub fn get_all(&self, key: &str) -> Option<Vec<String>>

Gets all references to a param of this name from the map.

pub fn latest_values(&self) -> ParamsMapIterRef<'_>

Gets an iterator for all the most-recently-added values on the map

pub fn get_str(&self, key: &str) -> Option<&str>

Gets a reference to the most-recently-added value of this param from the map.

pub fn remove(&mut self, key: &str) -> Option<Vec<String>>

Removes a value from the map.

pub fn to_query_string(&self) -> String

Converts the map to a query string.

Trait Implementations

impl Clone for ParamsMap

fn clone(&self) -> ParamsMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamsMap

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

Formats the value using the given formatter.

impl Default for ParamsMap

fn default() -> ParamsMap

Returns the “default value” for a type.

impl Eq for ParamsMap

impl<K, V> FromIterator<(K, V)> for ParamsMap

where K: Into<Cow<'static, str>>, V: Into<String>,

fn from_iter<T: IntoIterator<Item = (K, V)>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for ParamsMap

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoIterator for ParamsMap

type Item = (Cow<'static, str>, String)

The type of the elements being iterated over.

type IntoIter = ParamsMapIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a ParamsMap

type Item = (&'a Cow<'static, str>, &'a str)

The type of the elements being iterated over.

type IntoIter = ParamsMapIterRef<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for ParamsMap

fn eq(&self, other: &ParamsMap) -> 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.
