Struct tonic::metadata::GetAll

pub struct GetAll<'a, VE: ValueEncoding> { /* fields omitted */ }

A view to all values stored in a single entry.

This struct is returned by MetadataMap::get_all and MetadataMap::get_all_bin.

Implementations

impl<'a, VE: ValueEncoding> GetAll<'a, VE>

pub fn iter(&self) -> ValueIter<'a, VE>

Returns an iterator visiting all values associated with the entry.

Values are iterated in insertion order.

Examples

let mut map = MetadataMap::new();
map.insert("x-host", "hello.world".parse().unwrap());
map.append("x-host", "hello.earth".parse().unwrap());

let values = map.get_all("x-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());
