Struct rtic_sync::signal::SignalReader

source ·
pub struct SignalReader<'a, T: Copy> { /* private fields */ }
Expand description

Facilitates the async reading of values from the Signal.

Implementations§

source§

impl<'a, T: Copy> SignalReader<'a, T>

source

pub fn try_read(&mut self) -> Option<T>

Returns a pending value if present, or None if no value is available.

Upon read, the stored value is evicted.

source

pub async fn wait(&mut self) -> T

Wait for a new value to be written and read it.

If a value is already pending it will be returned immediately.

Upon read, the stored value is evicted.

source

pub async fn wait_fresh(&mut self) -> T

Wait for a new value to be written and read it.

If a value is already pending, it will be evicted and a new value must be written for the wait to resolve.

Upon read, the stored value is evicted.
