Trait Emit0

pub trait Emit0<R, C>
where
    (): Clone,
    C: Combiner<R> + 'static,
{
    type Output;

    // Required method
    fn emit(&self) -> Self::Output;
}

Emit trait for signals with slots that accept the corresponding number of arguments.

Required Associated Types

type Output

The return value of emit will be C::Output for Signals and Option<C::Output> for EmitHandles

Required Methods

fn emit(&self) -> Self::Output

Executes the signal’s underlying slots, passing clones of the given arguments to the slot functions.

Implementors

impl<R, C, G> Emit0<R, C> for EmitHandle<(), R, C, G>

where (): Clone, C: Combiner<R> + 'static, G: Ord + Send + Sync,

type Output = Option<<C as Combiner<R>>::Output>

impl<R, C, G> Emit0<R, C> for Signal<(), R, C, G>

where (): Clone, C: Combiner<R> + 'static, G: Ord + Send + Sync,

type Output = <C as Combiner<R>>::Output
