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(&self, name: impl AsRef<str>) -> Option<&str>

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

pub fn is_empty(&self) -> bool

pub fn push(&mut self, p: Param)

Inserts a URL parameter into the vector

Trait Implementations

impl Debug for Params

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

Formats the value using the given formatter.

impl Default for Params

fn default() -> Params

Returns the “default value” for a type.

impl 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 IndexMut<usize> for Params

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

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

impl IntoIterator for Params

type IntoIter = IntoIter<Param>

Which kind of iterator are we turning this into?

type Item = Param

The type of the elements being iterated over.

fn into_iter(self) -> <Params as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for Params

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