Struct actix_web::http::header::GetAll

pub struct GetAll<'a, T> where
    T: 'a,  { /* fields omitted */ }

A view to all values stored in a single entry.

This struct is returned by HeaderMap::get_all.

Methods

impl<'a, T> GetAll<'a, T> where     T: 'a,

Important traits for ValueIter<'a, T>

impl<'a, T> Iterator for ValueIter<'a, T> where
    T: 'a,  type Item = &'a T;

pub fn iter(&self) -> ValueIter<'a, T>

Returns an iterator visiting all values associated with the entry.

Values are iterated in insertion order.

Examples

let mut map = HeaderMap::new();
map.insert(HOST, "hello.world".parse().unwrap());
map.append(HOST, "hello.earth".parse().unwrap());

let values = map.get_all("host");
let mut iter = values.iter();
assert_eq!(&"hello.world", iter.next().unwrap());
assert_eq!(&"hello.earth", iter.next().unwrap());
assert!(iter.next().is_none());

Trait Implementations

impl<'a, 'b, T> IntoIterator for &'b GetAll<'a, T> where     'b: 'a,

impl<'a, T> PartialEq<GetAll<'a, T>> for GetAll<'a, T> where     T: PartialEq<T>,

fn eq(&self, other: &GetAll<'a, T>) -> bool

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
