Struct heapless::spsc::Consumer [−][src]
pub struct Consumer<'a, T, const N: usize> { /* fields omitted */ }
Expand description
A queue “consumer”; it can dequeue items from the queue
NOTE the consumer semantically owns the head
pointer of the queue
Implementations
Returns the item in the front of the queue, or None
if the queue is empty
Returns the item in the front of the queue, without checking if there are elements in the queue
See Queue::dequeue_unchecked
for safety
Returns if there are any items to dequeue. When this returns true
, at least the
first subsequent dequeue will succeed
Returns the item in the front of the queue without dequeuing, or None
if the queue is
empty
Examples
use heapless::spsc::Queue; let mut queue: Queue<u8, 235> = Queue::new(); let (mut producer, mut consumer) = queue.split(); assert_eq!(None, consumer.peek()); producer.enqueue(1); assert_eq!(Some(&1), consumer.peek()); assert_eq!(Some(1), consumer.dequeue()); assert_eq!(None, consumer.peek());
