struct Shared<T> {
    value: RwLock<T>,
    state: AtomicState,

Fields§

§value: RwLock<T>

The most recent value.

§state: AtomicState

The current version.

The lowest bit represents a “closed” state. The rest of the bits represent the current version.

§ref_count_rx: AtomicUsize

Tracks the number of Receiver instances.

§ref_count_tx: AtomicUsize

Tracks the number of Sender instances.

§notify_rx: BigNotify

Notifies waiting receivers that the value changed.

§notify_tx: Notify

Notifies any task listening for Receiver dropped events.
