pub struct MultiMut<'a> { /* private fields */ }Expand description
Provides mutable access to multiple different component storages from a single world.
Implementations§
Source§impl<'a> MultiMut<'a>
impl<'a> MultiMut<'a>
Sourcepub unsafe fn claim<T>(&mut self) -> Option<&'a mut <T as Component>::Storage>where
T: Component,
pub unsafe fn claim<T>(&mut self) -> Option<&'a mut <T as Component>::Storage>where
T: Component,
Claims exclusive access to a component storage.
§Safety
The caller must ensure that each component type is only claimed once, as doing otherwise may result in mutable aliases of the component storage. This is validated in debug builds.
Sourcepub unsafe fn claim_unknown(
&mut self,
type_id: ComponentTypeId,
) -> Option<&'a mut (dyn UnknownComponentStorage + 'static)>
pub unsafe fn claim_unknown( &mut self, type_id: ComponentTypeId, ) -> Option<&'a mut (dyn UnknownComponentStorage + 'static)>
Claims exclusive access to a component storage.
§Safety
