Struct ra_ap_la_arena::ArenaMap

pub struct ArenaMap<IDX, V> { /* fields omitted */ }

A map from arena indexes to some other type. Space requirement is O(highest index).

Implementations

impl<T, V> ArenaMap<Idx<T>, V>

pub fn insert(&mut self, idx: Idx<T>, t: V)

Inserts a value associated with a given arena index into the map.

pub fn get(&self, idx: Idx<T>) -> Option<&V>

Returns a reference to the value associated with the provided index if it is present.

pub fn get_mut(&mut self, idx: Idx<T>) -> Option<&mut V>

Returns a mutable reference to the value associated with the provided index if it is present.

pub fn values(&self) -> impl Iterator<Item = &V>

Returns an iterator over the values in the map.

pub fn values_mut(&mut self) -> impl Iterator<Item = &mut V>

Returns an iterator over mutable references to the values in the map.

pub fn iter(&self) -> impl Iterator<Item = (Idx<T>, &V)>

Returns an iterator over the arena indexes and values in the map.
