Trait gear_common::storage::IterableByKeyMap

pub trait IterableByKeyMap<Item> {
    type Key;
    type DrainIter: Iterator<Item = Item>;
    type Iter: Iterator<Item = Item>;

    // Required methods
    fn drain_key(key: Self::Key) -> Self::DrainIter;
    fn iter_key(key: Self::Key) -> Self::Iter;
}

Represents iterable logic for double key maps (Key1 -> Key2 -> Value).

Returns the iterators over specified (associated) type of the first key’s items.

Required Associated Types

type Key

Map’s first key type.

type DrainIter: Iterator<Item = Item>

Removal iterator type.

type Iter: Iterator<Item = Item>

Getting iterator type.

Required Methods

fn drain_key(key: Self::Key) -> Self::DrainIter

Creates the removal iterator over double map Items.

fn iter_key(key: Self::Key) -> Self::Iter

Creates the getting iterator over double map Items.

Object Safety

This trait is not object safe.
