Struct id_map::IdMap

pub struct IdMap<T> { /* fields omitted */ }

A container that gives each item a unique id.

Methods

impl<T> IdMap<T>

fn new() -> Self

Creates an empty IdMap<T>.

fn with_capacity(cap: usize) -> Self

Creates an IdMap<T> with the specified capacity.

fn insert(&mut self, val: T) -> Id

Inserts a value into the map and returns its id.

fn remove(&mut self, Id: Id) -> Option<T>

Removes an id from the map, returning its value if it was previously in the map.

fn ids(&self) -> Ids

An iterator over all ids in increasing order.

fn values(&self) -> Values<T>

An iterator over all values.

fn values_mut(&mut self) -> ValuesMut<T>

A mutable iterator over all values.

fn iter(&self) -> Iter<T>

An iterator over id-value pairs in order of increasing ids.

fn iter_mut(&mut self) -> IterMut<T>

A mutable iterator over id-value pairs in order of increasing ids.

fn contains(&self, Id: Id) -> bool

Returns true if the map contains a value for the specified id.

Trait Implementations
