Trait argdata::container_traits::MapContainer

pub trait MapContainer {
    type Key;
    type Value;
    fn get(&self, index: usize) -> Option<(&Self::Key, &Self::Value)>;
    fn len(&self) -> usize;
}

a random-access container containing pairs of keys and values.

Both a tuple of two Containers and a Container of tuples are considered MapContainers: Examples are (Vec<Key>, &[Val]) and Box<[(Key, Val)]>.

Associated Types

type Key

type Value

Required Methods

fn get(&self, index: usize) -> Option<(&Self::Key, &Self::Value)>

fn len(&self) -> usize

Implementations on Foreign Types
