Struct WithInputFromWrapper 

pub struct WithInputFromWrapper<S, T> { /* private fields */ }

Constructed in IntoSystem::with_input_from.

Implementations

impl<S, T> WithInputFromWrapper<S, T>

where S: for<'i> System, <S as System>::In: for<'i> SystemInput<Inner<'i> = &'i mut T>, T: Send + Sync + 'static,

pub fn new<M>( system: impl IntoSystem<<S as System>::In, <S as System>::Out, M, System = S>, ) -> WithInputFromWrapper<S, T>

Wraps the given system.

pub fn value(&self) -> Option<&T>

Returns a reference to the input value, if it has been initialized.

pub fn value_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to the input value, if it has been initialized.

Trait Implementations

impl<S, T> System for WithInputFromWrapper<S, T>

where S: for<'i> System, <S as System>::In: for<'i> SystemInput<Inner<'i> = &'i mut T>, T: FromWorld + Send + Sync + 'static,

type In = ()

The system’s input.

type Out = <S as System>::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: <<WithInputFromWrapper<S, T> as System>::In as SystemInput>::Inner<'_>, world: UnsafeWorldCell<'_>, ) -> Result<<WithInputFromWrapper<S, T> 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 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.

unsafe fn validate_param_unsafe( &mut self, world: UnsafeWorldCell<'_>, ) -> Result<(), SystemParamValidationError>

Validates that all parameters can be acquired and that system can run without panic. Built-in executors use this to prevent invalid systems from running.

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 type_id(&self) -> TypeId

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 validate_param( &mut self, world: &World, ) -> Result<(), SystemParamValidationError>

Safe version of System::validate_param_unsafe. that runs on exclusive, single-threaded world pointer.

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

Returns the system’s default system sets.
