fn map<F, B>(self, f: F) -> LiftSignal<F, A, B> where F: 'static + Send + Fn(A) -> B, B: 'static + Send + Clone

Alias of lift

fn zip<SB, B>(self, right: SB) -> Box<Signal<(Value<A>, Value<B>)>> where SB: 'static + Signal<B>, B: 'static + Send + Clone

Takes two input signals and returns a signal containing 2-tuples of elements from the input signals.

fn enumerate(self) -> Box<Signal<(usize, A)>>

Same as Iterator::enumerate.

fn filter<F>(self, f: F) -> Box<Signal<Option<A>>> where F: 'static + Send + Fn(&A) -> bool

fn inspect<F>(self, f: F) -> Box<Signal<A>> where F: 'static + Send + Fn(&A) -> bool

Pass each value in a signal to F before sending it to an output signal.
