pub struct AsyncSemaphore { /* private fields */ }

Async-capable wrappers for OSAL primitives. An async-capable semaphore wrapping an Arc<Semaphore>.

Implementations

impl AsyncSemaphore

pub fn new(max_count: u32, initial_count: u32) -> Result<Self>

Creates an AsyncSemaphore with max_count and initial_count.

Errors

Returns the underlying OSAL error if the semaphore cannot be created.

pub fn signal(&self) -> OsalRsBool

Signals (increments) the semaphore and wakes any async waiter.

pub fn wait_async(&self) -> WaitFuture<'_>

Returns a Future that resolves when the semaphore count becomes > 0.
