Struct frappe::SignalNested

pub struct SignalNested<T>(_);

A signal that contains a signal, and allows sampling the inner signal directly.

This is produced by Signal::switch

impl<T: Clone + 'static> Signal<T> for SignalNested<T>

fn sample(&self) -> T

Sample by value.

fn sample_with<F, R>(&self, cb: F) -> R where
    F: FnOnce(Cow<T>) -> R, 

Sample by reference.

fn map<F, R>(&self, f: F) -> SignalFn<R> where
    F: Fn(Cow<T>) -> R + 'static,
    R: Clone,
    T: Clone + 'static, 

Maps a signal with the provided function.

fn snapshot<S, F, R>(&self, trigger: &Stream<S>, f: F) -> Stream<R> where
    F: Fn(Cow<T>, Cow<S>) -> R + 'static,
    S: Clone + 'static,
    R: Clone + 'static,
    T: Clone + 'static,

fn switch<U>(&self) -> SignalNested<U> where
    T: Signal<U> + Into<SignalAny<U>>,
    U: Clone, 

Creates a new signal that samples the inner value of a nested signal.
