RwSignal

Struct RwSignal 

Source
pub struct RwSignal<T> { /* private fields */ }
Expand description

A signal that can be read and written.

Created with RwSignal::new, or split into a ReadSignal and a WriteSignal by signal_local. Cloning the handle is cheap, and every clone names the same signal.

Implementations§

Source§

impl<T: 'static> RwSignal<T>

Source

pub fn new(value: T) -> RwSignal<T>

Creates a signal holding value, under the current owner.

The signal is disposed when that owner is cleaned up. Handles that outlive it keep the value readable but notify nothing. With no current owner nothing disposes it, and its entry in the runtime stays until the thread ends.
