Trait Implementations

impl<T> ComponentResourceApi for MapStorage<T>

type Component = T

The type of data stored for each entity.

fn get(&self, entity: Entity) -> Option<&T>

Gets a shared reference to the component associated with the given entity, if present.

unsafe fn get_unchecked(&self, entity: Entity) -> &T

Gets a shared reference to the component associated with the given entity without performing any bounds or liveness checking.

fn get_mut(&mut self, entity: Entity) -> Option<&mut T>

Gets a mutable reference to the component associated with the given entity, if present.

unsafe fn get_unchecked_mut(&mut self, entity: Entity) -> &mut T

Gets a mutable reference to the component associated with the given entity without performing any bounds or liveness checking.
