Struct bevy::ecs::component::ComponentIdFor
pub struct ComponentIdFor<T>where
T: Component,{ /* private fields */ }
Expand description
Initialize and fetch a ComponentId
for a specific type.
Example
#[derive(Component)]
struct Player;
fn my_system(component_id: Local<ComponentIdFor<Player>>) {
let component_id: ComponentId = component_id.into();
// ...
}
Trait Implementations§
§impl<T> Deref for ComponentIdFor<T>where
T: Component,
impl<T> Deref for ComponentIdFor<T>where T: Component,
§type Target = ComponentId
type Target = ComponentId
The resulting type after dereferencing.
§fn deref(&self) -> &<ComponentIdFor<T> as Deref>::Target
fn deref(&self) -> &<ComponentIdFor<T> as Deref>::Target
Dereferences the value.
§impl<T> From<ComponentIdFor<T>> for ComponentIdwhere
T: Component,
impl<T> From<ComponentIdFor<T>> for ComponentIdwhere T: Component,
§fn from(to_component_id: ComponentIdFor<T>) -> ComponentId
fn from(to_component_id: ComponentIdFor<T>) -> ComponentId
Converts to this type from the input type.
§impl<T> FromWorld for ComponentIdFor<T>where
T: Component,
impl<T> FromWorld for ComponentIdFor<T>where T: Component,
§fn from_world(world: &mut World) -> ComponentIdFor<T>
fn from_world(world: &mut World) -> ComponentIdFor<T>
Creates
Self
using data from the given WorldAuto Trait Implementations§

Blanket Implementations§
§impl<T, U> AsBindGroupShaderType<U> for Twhere
U: ShaderType,
&'a T: for<'a> Into<U>,
impl<T, U> AsBindGroupShaderType<U> for Twhere U: ShaderType, &'a T: for<'a> Into<U>,
§fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U
fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U
Return the
T
ShaderType
for self
. When used in AsBindGroup
derives, it is safe to assume that all images in self
exist.§impl<T> Downcast for Twhere
T: Any,
impl<T> Downcast for Twhere T: Any,
§fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>
Convert
Box<dyn Trait>
(where Trait: Downcast
) to Box<dyn Any>
. Box<dyn Any>
can
then be further downcast
into Box<ConcreteType>
where ConcreteType
implements Trait
.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
Convert
Rc<Trait>
(where Trait: Downcast
) to Rc<Any>
. Rc<Any>
can then be
further downcast
into Rc<ConcreteType>
where ConcreteType
implements Trait
.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait
(where Trait: Downcast
) to &Any
. This is needed since Rust cannot
generate &Any
’s vtable from &Trait
’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait
(where Trait: Downcast
) to &Any
. This is needed since Rust cannot
generate &mut Any
’s vtable from &mut Trait
’s.
