A trait implemented by all typemaps that provides all basic typemap functions

Associated Types

type Key: MapKey<Map = Self>

Required methods

fn new() -> Self

Creates a new typemap

fn insert<T: TypedKeyTrait<Self::Key>>(&mut self, value: T::Value)

Inserts a value into the typemap with the given key

fn get<T: TypedKeyTrait<Self::Key>>(&self) -> Option<&T::Value>

Returns a reference to a value from the type map with the given provided key

fn get_mut<T: TypedKeyTrait<Self::Key>>(&mut self) -> Option<&mut T::Value>

Returns a mutable reference to a value from the type map with the given provided key

fn remove<T: TypedKeyTrait<Self::Key>>(&mut self) -> Option<T::Value>

Removes a value from the map for the given key

fn contains_key<T: TypedKeyTrait<Self::Key>>(&self) -> bool

Returns if the map contains a given key
