Expand description

The trait defining how storage works.

Type Arguments

  • K is the key being stored.
  • V is the value being stored.

Associated Types

type Iter: Clone + Iterator<Item = (K, *const V)>[src]

Immutable iterator over storage. Uses raw pointers (unsafe) since we don’t have GATs.

type IterMut: Iterator<Item = (K, *mut V)>[src]

Mutable iterator over storage. Uses raw pointers (unsafe) since we don’t have GATs.

Required methods

fn insert(&mut self, key: K, value: V) -> Option<V>[src]

This is the storage abstraction for Map::insert.

fn get(&self, key: K) -> Option<&V>[src]

This is the storage abstraction for Map::get.

fn get_mut(&mut self, key: K) -> Option<&mut V>[src]

This is the storage abstraction for Map::get_mut.

fn remove(&mut self, key: K) -> Option<V>[src]

This is the storage abstraction for Map::remove.

fn clear(&mut self)[src]

This is the storage abstraction for Map::clear.

fn iter(&self) -> Self::Iter[src]

This is the storage abstraction for Map::iter.

fn iter_mut(&mut self) -> Self::IterMut[src]

This is the storage abstraction for Map::iter_mut.
