Trait KeyedCollection 

pub trait KeyedCollection {
    type Key;
    type Value;
}

A keyed collection without any operations defined.

A keyed collection is just a key-value map. We however use the name KeyedCollection instead of Map to distinguish maps from vectors and stable vectors, which also are keyed collections but with slightly different sets of operations.

Required Associated Types

type Key

Type of the keys in the keyed collection.

type Value

Type of the values in the keyed collection.
