Struct fixed_map::storage::OptionStorage

pub struct OptionStorage<K, V> where
    K: Key<K, V>,  { /* fields omitted */ }

Storage for Option<T>s.

Trait Implementations

impl<K, V> Storage<Option<K>, V> for OptionStorage<K, V> where     K: Key<K, V>,

type Iter = Iter<K, V>

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

type IterMut = IterMut<K, V>

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

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

This is the storage abstraction for Map::insert.

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

This is the storage abstraction for Map::get.

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

This is the storage abstraction for Map::get_mut.

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

This is the storage abstraction for Map::remove.

fn clear(&mut self)

This is the storage abstraction for Map::clear.

fn iter(&self) -> Self::Iter

This is the storage abstraction for Map::iter.

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

This is the storage abstraction for Map::iter_mut.

impl<K, V> Eq for OptionStorage<K, V> where     K: Key<K, V>,     K::Storage: Eq,     V: Eq,

impl<K, V> Clone for OptionStorage<K, V> where     K: Key<K, V>,     K::Storage: Clone,     V: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K, V> PartialEq<OptionStorage<K, V>> for OptionStorage<K, V> where     K: Key<K, V>,     K::Storage: PartialEq,     V: PartialEq,

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<K, V> Default for OptionStorage<K, V> where     K: Key<K, V>,

fn default() -> Self

Returns the "default value" for a type.
