Struct futures_intrusive::channel::shared::StateReceiveFuture

pub struct StateReceiveFuture<MutexType, T> { /* private fields */ }

A Future that is returned by the receive function on a state broadcast channel. The future gets resolved with Some((state_id, state)) when a value could be received from the channel.

state represents the new state which had been retrieved from the channel.

state_id is the StateId which can be passed as a parameter to receive() in order to fetch the next state from the channel.

If the channels gets closed and no items are still enqueued inside the channel, the future will resolve to None.
