Struct Params

pub struct Params(pub Vec<Param>);

A Vec of Param returned by a route match. There are two ways to retrieve the value of a parameter:

1. by the name of the parameter

 let user = params.get("user"); // defined by :user or *user

2. by the index of the parameter. This way you can also get the name (key)

 let third_key = &params[2].key;   // the name of the 3rd parameter
 let third_value = &params[2].value; // the value of the 3rd parameter

Tuple Fields

0: Vec<Param>

Implementations

impl Params

pub fn get<K: AsRef<str>>(&self, name: K) -> Option<&str>

Returns the value of the first Param whose key matches the given name.

pub fn is_empty(&self) -> bool

pub fn push<P: Into<Param>>(&mut self, p: P)

Inserts a URL parameter into the vector

pub fn len(&self) -> usize

pub fn first(&self) -> Option<&Param>

Trait Implementations

impl Clone for Params

fn clone(&self) -> Params

Returns a duplicate of the value.

const 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<'a> Default for Params

fn default() -> Self

Returns the “default value” for a type.

impl<'a, 'b> FromIterator<(&'a Cow<'b, str>, &'a Cow<'b, str>)> for Params

where 'b: 'a,

fn from_iter<T: IntoIterator<Item = (&'a Cow<'b, str>, &'a Cow<'b, str>)>>( iter: T, ) -> Self

Creates a value from an iterator.

impl<'a> FromIterator<(&'a str, &'a str)> for Params

fn from_iter<T: IntoIterator<Item = (&'a str, &'a str)>>(iter: T) -> Self

Creates a value from an iterator.

impl<'a> FromIterator<(Cow<'a, str>, Cow<'a, str>)> for Params

fn from_iter<T: IntoIterator<Item = (Cow<'a, str>, Cow<'a, str>)>>( iter: T, ) -> Self

Creates a value from an iterator.

impl<'a> Index<usize> for Params

type Output = Param

The returned type after indexing.

fn index(&self, i: usize) -> &Param

Performs the indexing (container[index]) operation.

impl<'a> IndexMut<usize> for Params

fn index_mut(&mut self, i: usize) -> &mut Param

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Params

fn eq(&self, other: &Params) -> bool

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

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

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