Struct ArcReadSignal 

pub struct ArcReadSignal<T>
where
    T: 'static,
{ /* private fields */ }

Refcount-backed read-only handle. Clone-cheap (Rc bump), !Copy. The companion to ArcRwSignal::read_only.

Implementations

impl<T> ArcReadSignal<T>

where T: 'static,

pub fn with<R>(&self, f: impl FnOnce(&T) -> R) -> R

pub fn with_untracked<R>(&self, f: impl FnOnce(&T) -> R) -> R

impl<T> ArcReadSignal<T>

where T: 'static + Clone,

pub fn get(&self) -> T

pub fn get_untracked(&self) -> T

Trait Implementations

impl<T> Clone for ArcReadSignal<T>

where T: 'static,

fn clone(&self) -> ArcReadSignal<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> From<ArcReadSignal<T>> for ReadSignal<T>

where T: 'static,

fn from(arc_r: ArcReadSignal<T>) -> ReadSignal<T>

Build an arena-backed read handle whose underlying signal is shared with the source [ArcReadSignal]. Writes through any handle (the Arc, another converted WriteSignal, …) propagate to this handle’s subscribers via the shared Arc inner.
