Required Associated Types§
Required Methods§
sourcefn into_system(this: Self) -> Self::System
fn into_system(this: Self) -> Self::System
Turns this value into its corresponding System
.
Provided Methods§
sourcefn pipe<B, Final, MarkerB>(
self,
system: B
) -> PipeSystem<Self::System, B::System>where
B: IntoSystem<Out, Final, MarkerB>,
fn pipe<B, Final, MarkerB>(
self,
system: B
) -> PipeSystem<Self::System, B::System>where
B: IntoSystem<Out, Final, MarkerB>,
Pass the output of this system A
into a second system B
, creating a new compound system.
The second system must have In<T>
as its first parameter,
where T
is the return type of the first system.
sourcefn map<T, F>(self, f: F) -> AdapterSystem<F, Self::System>
fn map<T, F>(self, f: F) -> AdapterSystem<F, Self::System>
Pass the output of this system into the passed function f
, creating a new system that
outputs the value returned from the function.
// Ignores the output of a system that may fail.
schedule.add_systems(my_system.map(drop));
fn my_system(res: Res<T>) -> Result<(), Err> {
// ...
}
sourcefn system_type_id(&self) -> TypeId
fn system_type_id(&self) -> TypeId
Get the TypeId
of the System
produced after calling into_system
.
