Trait Implementations

impl<E, P> TriggerCriterion for PropertyChangeTrigger<E, P>

where E: Entity, P: Property<E>,

type Observation = PropertyChangeTriggerEvent<E, P>

The data that represents what is observed when the criterion is met. This data is passed to the handler installed for this criterion.

fn install<F>(self, context: &mut Context, on_match: F)

where F: Fn(&mut Context, Self::Observation) + 'static,

Install the criterion’s monitoring logic in context.

fn emit_with<Ev, F>(self, make_event: F) -> Trigger<Self, Ev, F>

where Ev: IxaEvent, F: Fn(Self::Observation) -> Ev + 'static,

Bind this criterion to a constructor for a concrete user event.

fn emit_default<Ev>(self) -> Trigger<Self, Ev, impl Fn(Self::Observation) -> Ev>

where Ev: IxaEvent + Default,

Bind this criterion to a default-valued concrete user event.

fn emit_value<Ev>( self, event: Ev, ) -> Trigger<Self, Ev, impl Fn(Self::Observation) -> Ev>

where Ev: IxaEvent,

Bind this criterion to a constant concrete user event value.
