Struct web_embedded_hal::components::Signal

pub struct Signal<T> { /* private fields */ }

Synchronization primitive. Allows creating awaitable signals that may be passed between tasks. For a simple use-case where the receiver is only ever interested in the latest value of something, Signals work well. For more advanced use cases, you might want to use Channel instead..

Signals are generally declared as being a static const and then borrowed as required.

Implementations

impl<T> Signal<T>

pub const fn new() -> Self

impl<T: Send> Signal<T>

pub fn signal(&self, val: T)

pub fn wait(&self) -> impl Future<Output = T> + '_

Future that completes when this Signal has been signaled.

pub fn signaled(&self) -> bool
