Struct hyper::header::GetAll

source ·
pub struct GetAll<'a, T> {
    map: &'a HeaderMap<T>,
    index: Option<usize>,
}
Expand description

A view to all values stored in a single entry.

This struct is returned by HeaderMap::get_all.

Implementations§

source§

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

source

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());

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.
