Struct bevy::ecs::system::CombinatorSystem

pub struct CombinatorSystem<Func, A, B> { /* private fields */ }

A System defined by combining two other systems. The behavior of this combinator is specified by implementing the Combine trait. For a full usage example, see the docs for Combine.

Implementations

impl<Func, A, B> CombinatorSystem<Func, A, B>

pub const fn new( a: A, b: B, name: Cow<'static, str> ) -> CombinatorSystem<Func, A, B>

Creates a new system that combines two inner systems.

The returned system will only be usable if Func implements Combine<A, B>.

Trait Implementations

impl<Func, A, B> Clone for CombinatorSystem<Func, A, B>

where A: Clone, B: Clone,

fn clone(&self) -> CombinatorSystem<Func, A, B>

Clone the combined system. The cloned instance must be .initialize()d before it can run.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A, B, Func> ReadOnlySystem for CombinatorSystem<Func, A, B>

where Func: Combine<A, B> + 'static, A: ReadOnlySystem, B: ReadOnlySystem,

SAFETY: Both systems are read-only, so any system created by combining them will only read from the world.

fn run_readonly(&mut self, input: Self::In, world: &World) -> Self::Out

Runs this system with the given input in the world.

impl<A, B, Func> System for CombinatorSystem<Func, A, B>

where Func: Combine<A, B> + 'static, A: System, B: System,

type In = <Func as Combine<A, B>>::In

The system’s input. See In for FunctionSystems.

type Out = <Func as Combine<A, B>>::Out

The system’s output.

fn name(&self) -> Cow<'static, str>

Returns the system’s name.

fn component_access(&self) -> &Access<ComponentId>

Returns the system’s component Access.

fn archetype_component_access(&self) -> &Access<ArchetypeComponentId>

Returns the system’s archetype component Access.

fn is_send(&self) -> bool

Returns true if the system is Send.

fn is_exclusive(&self) -> bool

Returns true if the system must be run exclusively.

fn has_deferred(&self) -> bool

Returns true if system as deferred buffers

unsafe fn run_unsafe( &mut self, input: <CombinatorSystem<Func, A, B> as System>::In, world: UnsafeWorldCell<'_> ) -> <CombinatorSystem<Func, A, B> as System>::Out

Runs the system with the given input in the world. Unlike System::run, this function can be called in parallel with other systems and may break Rust’s aliasing rules if used incorrectly, making it unsafe to call.

fn run<'w>( &mut self, input: <CombinatorSystem<Func, A, B> as System>::In, world: &'w mut World ) -> <CombinatorSystem<Func, A, B> as System>::Out

Runs the system with the given input in the world.

fn apply_deferred(&mut self, world: &mut World)

Applies any Deferred system parameters (or other system buffers) of this system to the world.

fn initialize(&mut self, world: &mut World)

Initialize the system.

fn update_archetype_component_access(&mut self, world: UnsafeWorldCell<'_>)

Update the system’s archetype component Access.

fn check_change_tick(&mut self, change_tick: Tick)

Checks any Ticks stored on this system and wraps their value if they get too old.

fn default_system_sets(&self) -> Vec<Interned<dyn SystemSet>>

Returns the system’s default system sets.

fn get_last_run(&self) -> Tick

Gets the tick indicating the last time this system ran.

fn set_last_run(&mut self, last_run: Tick)

Overwrites the tick indicating the last time this system ran.

fn type_id(&self) -> TypeId

Returns the TypeId of the underlying system type.
