Struct ExclusiveFunctionSystem

pub struct ExclusiveFunctionSystem<Marker, F>
where
    F: ExclusiveSystemParamFunction<Marker>,
{ /* private fields */ }

A function system that runs with exclusive World access.

You get this by calling IntoSystem::into_system on a function that only accepts ExclusiveSystemParams.

ExclusiveFunctionSystem must be .initialized before they can be run.

Trait Implementations

impl<Marker, F> System for ExclusiveFunctionSystem<Marker, F>

where Marker: 'static, F: ExclusiveSystemParamFunction<Marker>,

type In = <F as ExclusiveSystemParamFunction<Marker>>::In

The system’s input. See In for FunctionSystems.

type Out = <F as ExclusiveSystemParamFunction<Marker>>::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: Self::In, _world: UnsafeWorldCell<'_>, ) -> Self::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(&mut self, input: Self::In, world: &mut World) -> Self::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 queue_deferred(&mut self, _world: DeferredWorld<'_>)

Enqueues any Deferred system parameters (or other system buffers) of this system into the world’s command buffer.

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<InternedSystemSet>

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.
