Trait Emit4 

pub trait Emit4<R, C, T0, T1, T2, T3>
where
    (T0, T1, T2, T3): Clone,
    C: Combiner<R> + 'static,
{
    type Output;

    // Required method
    fn emit(&self, a: T0, b: T1, c: T2, d: T3) -> 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, a: T0, b: T1, c: T2, d: T3) -> Self::Output

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