Trait Implementations§
Source§impl<P: SystemParam, B: SystemParamBuilder<P>> SystemParamBuilder<If<P>> for IfBuilder<B>
impl<P: SystemParam, B: SystemParamBuilder<P>> SystemParamBuilder<If<P>> for IfBuilder<B>
Source§fn build(self, world: &mut World) -> <If<P> as SystemParam>::State
fn build(self, world: &mut World) -> <If<P> as SystemParam>::State
Registers any
World access used by this SystemParam
and creates a new instance of this param’s State.Source§fn build_state(self, world: &mut World) -> SystemState<P>
fn build_state(self, world: &mut World) -> SystemState<P>
Create a
SystemState from a SystemParamBuilder.
To create a system, call SystemState::build_system on the result.Source§fn build_system<Marker, In, Out, Func>(
self,
func: Func,
) -> IntoBuilderSystem<Marker, In, Out, Func, Self>where
Self: 'static,
Func: SystemParamFunction<Marker, Param = P>,
fn build_system<Marker, In, Out, Func>(
self,
func: Func,
) -> IntoBuilderSystem<Marker, In, Out, Func, Self>where
Self: 'static,
Func: SystemParamFunction<Marker, Param = P>,

Source§fn into_any(self: Box<T>) -> Box<dyn Any>
fn into_any(self: Box<T>) -> Box<dyn Any>
Converts
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be
downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Converts
Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further
downcast into Rc<ConcreteType> where ConcreteType implements Trait.Source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Converts
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.Source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Converts
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.Source§impl<T> DowncastSend for T

fn build_template( &self, _context: &mut TemplateContext<'_, '_>, ) -> Result<<T as Template>::Output, BevyError>
Uses this template and the given
entity context to produce a Template::Output.Source§fn clone_template(&self) -> T
fn clone_template(&self) -> T
Clones this template. See
