Struct Queue 

pub struct Queue<T: Sized + Send> { /* private fields */ }

A queue with a finite size.

Implementations

impl<T: Sized + Send> Queue<T>

pub fn new(max_size: usize) -> Result<Queue<T>, FreeRtosError>

pub unsafe fn from_raw_handle(handle: FreeRtosQueueHandle) -> Self

Safety

handle must be a valid FreeRTOS regular queue handle (not semaphore or mutex).

The item size of the queue must match the size of T.

pub fn raw_handle(&self) -> FreeRtosQueueHandle

pub fn send<D: DurationTicks>( &self, item: T, max_wait: D, ) -> Result<(), SendError<T>>

Send an item to the end of the queue. Wait for the queue to have empty space for it.

pub fn send_from_isr( &self, context: &mut InterruptContext, item: T, ) -> Result<(), SendError<T>>

Send an item to the end of the queue, from an interrupt.

pub fn receive<D: DurationTicks>(&self, max_wait: D) -> Result<T, FreeRtosError>

Wait for an item to be available on the queue.

pub fn len(&self) -> u32

Get the number of messages in the queue.
