Struct PhysicalActionRef

pub struct PhysicalActionRef<T: Sync>(/* private fields */);

A reference to a physical action. This thing is cloneable and can be sent to async threads. The contained action reference is unique and protected by a lock. All operations on the action are

See crate::ReactionCtx::spawn_physical_thread.

Trait Implementations

impl<T: Clone + Sync> Clone for PhysicalActionRef<T>

fn clone(&self) -> PhysicalActionRef<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Sync> ReactionTrigger<T> for PhysicalActionRef<T>

fn is_present(&self, now: &EventTag, start: &Instant) -> bool

Returns whether the trigger is present, given that the current logical time is the parameter.

fn get_value(&self, now: &EventTag, start: &Instant) -> Option<T>

where T: Copy,

Copies the value out, if it is present. Whether a value is present is not in general the same thing as whether this trigger Self::is_present. See crate::ReactionCtx::get.

fn use_value_ref<O>( &self, now: &EventTag, start: &Instant, action: impl FnOnce(Option<&T>) -> O, ) -> O

Execute an action using the current value of this trigger. The closure is called even if the value is absent (with a None argument).
