Struct legion::world::EntryRef [−][src]
Provides safe read-only access to an entity’s components.
Implementations
impl<'a> EntryRef<'a>[src]
pub fn archetype(&self) -> &Archetype[src]
Returns the entity’s archetype.
pub fn location(&self) -> EntityLocation[src]
Returns the entity’s location.
pub fn into_component<T: Component>(self) -> Result<&'a T, ComponentError>[src]
Returns a reference to one of the entity’s components.
pub unsafe fn into_component_unchecked<T: Component>(
self
) -> Result<&'a mut T, ComponentError>[src]
self
) -> Result<&'a mut T, ComponentError>
Returns a mutable reference to one of the entity’s components.
Safety
This function bypasses static borrow checking. The caller must ensure that the component reference will not be mutably aliased.
pub fn get_component<T: Component>(&self) -> Result<&T, ComponentError>[src]
Returns a reference to one of the entity’s components.
pub unsafe fn get_component_unchecked<T: Component>(
&self
) -> Result<&mut T, ComponentError>[src]
&self
) -> Result<&mut T, ComponentError>
Returns a mutable reference to one of the entity’s components.
Safety
This function bypasses static borrow checking. The caller must ensure that the component reference will not be mutably aliased.
