Struct InfallibleObserverWrapper

pub struct InfallibleObserverWrapper<E, B, S, Out> { /* private fields */ }

A wrapper that converts an observer system that returns () into one that returns Ok(()).

Implementations

impl<E, B, S, Out> InfallibleObserverWrapper<E, B, S, Out>

pub fn new(observer: S) -> Self

Create a new InfallibleObserverWrapper.

Trait Implementations

impl<E, B, S, Out> System for InfallibleObserverWrapper<E, B, S, Out>

where S: ObserverSystem<E, B, Out>, E: Send + Sync + 'static, B: Bundle, Out: Send + Sync + 'static,

type In = Trigger<'static, E, B>

The system’s input.

type Out = Result<(), BevyError>

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 has deferred buffers.

unsafe fn run_unsafe( &mut self, input: SystemIn<'_, Self>, 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 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)

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 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 default_system_sets(&self) -> Vec<InternedSystemSet>

Returns the system’s default system sets.

fn type_id(&self) -> TypeId

Returns the TypeId of the underlying system type.

fn run(&mut self, input: SystemIn<'_, Self>, world: &mut World) -> Self::Out

Runs the system with the given input in the world.

fn run_without_applying_deferred( &mut self, input: SystemIn<'_, Self>, world: &mut World, ) -> Self::Out

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.
