Struct BuilderSystem 

pub struct BuilderSystem<Marker, In, Out, Func, Builder>
where
    Func: SystemParamFunction<Marker>,
    Builder: SystemParamBuilder<<Func as SystemParamFunction<Marker>>::Param>,
{ /* private fields */ }

A System created from a SystemParamBuilder whose state is not initialized until the first run.

Implementations

impl<Marker, In, Out, Func, Builder> BuilderSystem<Marker, In, Out, Func, Builder>

where Func: SystemParamFunction<Marker>, Builder: SystemParamBuilder<<Func as SystemParamFunction<Marker>>::Param>,

pub fn new( builder: Builder, func: Func, ) -> BuilderSystem<Marker, In, Out, Func, Builder>

Returns a new BuilderSystem given a system param builder and a system function

fn run_readonly( &mut self, input: <Self::In as SystemInput>::Inner<'_>, world: &World, ) -> Result<Self::Out, RunSystemError>

Runs this system with the given input in the world.

impl<Marker, In, Out, Func, Builder> System for BuilderSystem<Marker, In, Out, Func, Builder>

where Marker: 'static, In: SystemInput + 'static, Out: 'static, Func: SystemParamFunction<Marker>, <Func as SystemParamFunction<Marker>>::In: FromInput<In>, <Func as SystemParamFunction<Marker>>::Out: IntoResult<Out>, Builder: SystemParamBuilder<<Func as SystemParamFunction<Marker>>::Param> + Send + Sync + 'static,

type In = In

The system’s input.

type Out = Out

The system’s output.

fn name(&self) -> DebugName

Returns the system’s name.

fn flags(&self) -> SystemStateFlags

Returns the SystemStateFlags of the system.

unsafe fn run_unsafe( &mut self, input: <<BuilderSystem<Marker, In, Out, Func, Builder> as System>::In as SystemInput>::Inner<'_>, world: UnsafeWorldCell<'_>, ) -> Result<<BuilderSystem<Marker, In, Out, Func, Builder> as System>::Out, RunSystemError>

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 refresh_hotpatch(&mut self)

Available on crate feature hotpatching only.

Refresh the inner pointer based on the latest hot patch jump table

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) -> FilteredAccessSet

Initialize the system.

fn check_change_tick(&mut self, check: CheckChangeTicks)

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

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 system_type(&self) -> TypeId

Returns the TypeId of the underlying system type.

fn type_id(&self) -> TypeId

👎Deprecated since 0.19.0:

Use system_type instead. This method shadows Any::type_id and will be removed in a future release.

Returns the TypeId of the underlying system type.

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 has deferred buffers.

fn run( &mut self, input: <Self::In as SystemInput>::Inner<'_>, world: &mut World, ) -> Result<Self::Out, RunSystemError>

Runs the system with the given input in the world.

fn run_without_applying_deferred( &mut self, input: <Self::In as SystemInput>::Inner<'_>, world: &mut World, ) -> Result<Self::Out, RunSystemError>

Runs the system with the given input in the world.

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

Returns the system’s default system sets.
