ConditionWithAccess

Struct ConditionWithAccess 

Source
pub struct ConditionWithAccess {
    pub condition: BoxedCondition,
    pub access: FilteredAccessSet,
}
Expand description

A BoxedCondition stored alongside the access returned from System::initialize.

Fields§

§condition: BoxedCondition

The condition itself.

§access: FilteredAccessSet

The access returned by System::initialize. This will be empty if the system has not been initialized yet.

Implementations§

Source§

impl ConditionWithAccess

Source

pub const fn new(condition: BoxedCondition) -> Self

impl System for ConditionWithAccess

Source§

type In = ()

Source§

type Out = bool

Source§

fn name(&self) -> DebugName

Source§

unsafe fn run_unsafe( &mut self, input: SystemIn<'_, Self>, world: UnsafeWorldCell<'_>, ) -> Result<Self::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. Read more

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

Returns the system’s default system sets. Read more
Source§

fn get_last_run(&self) -> Tick

Gets the tick indicating the last time this system ran.

Source§

fn is_send(&self) -> bool

Returns true if the system is Send.
Source§

Source§

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

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