Struct ChannelInner 

Source 
struct ChannelInner<T: Send> {
    buffer: ArrayQueue<T>,
    send_waitq: WaitQueue,
    recv_waitq: WaitQueue,
    status: AtomicU8,
    sender_count: AtomicUsize,
    receiver_count: AtomicUsize,
}
Expand description

Shared inner state for the typed MPMC channel.

Fields§

§buffer: ArrayQueue<T>

Bounded message queue.

§send_waitq: WaitQueue

Tasks blocked because the buffer is full (waiting to send).

§recv_waitq: WaitQueue

Tasks blocked because the buffer is empty (waiting to receive).

§status: AtomicU8

Channel status: CONNECTED / SENDER_GONE / RECEIVER_GONE.

§sender_count: AtomicUsize

Number of live Sender endpoints.

§receiver_count: AtomicUsize

Number of live Receiver endpoints.
