Struct cfrp::primitives::fork::Branch

pub struct Branch<A> where
    A: 'static + Send,  { /* fields omitted */ }

A data source of type A which can be used as input more than once

This operation is equivalent to a "let" binding, or variable assignment. Branch implements Clone, and each clone runs in its own thread.

Branches are returned when add is called on a Builder

Methods

fn add_to(self, builder: &Builder) -> Branch<A>

Sugar for Builder::add

fn async(self, builder: &Builder) -> Branch<A>

Sugar for Builder::async

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, 

Filter an input stream by a predicate function F.

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.

impl<A> Clone for Branch<A> where
    A: 'static + Send + Clone, 

fn clone(&self) -> Branch<A>

Returns a copy of the value.

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

Performs copy-assignment from source.
