Struct tonic::metadata::GetAll [−][src]
pub struct GetAll<'a, VE: ValueEncoding> { /* fields omitted */ }
Expand description
A view to all values stored in a single entry.
This struct is returned by MetadataMap::get_all
and
MetadataMap::get_all_bin
.
Implementations
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());
Trait Implementations

type Item = &'a MetadataValue<VE>
