Struct Map 

pub struct Map<T: Handled> {
    value_by_id: HashMap<Id, T>,
    id_by_handle: HashMap<Handle, Id>,
}

Fields

value_by_id: HashMap<Id, T>

id_by_handle: HashMap<Handle, Id>

Implementations

impl<T: Handled> Map<T>

pub fn get<Q>(&self, k: &Q) -> Option<&T>

where Q: AsHandleOrId,

pub fn insert_new(&mut self, value: T) -> Option<HandleOrId>

Inserts value into Map unless its id or one of its handles is already present in the map. In that case the id or one of the conflicting handles is returned.

pub fn values(&self) -> Values<'_, Id, T>

Returns an Iterator over the values of this map.

Trait Implementations

impl<T: Clone + Handled> Clone for Map<T>

fn clone(&self) -> Map<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Handled> Default for Map<T>

fn default() -> Self

Returns the “default value” for a type.
