Enum Selected

pub enum Selected {
    Waiting,
    Aborted,
    Disconnected,
    Operation(Operation),
}

🔬This is a nightly-only experimental API. (mpmc_channel #126840)

Expand description

Current state of a blocking operation.

Variants§

§

Waiting

🔬This is a nightly-only experimental API. (mpmc_channel #126840)

Still waiting for an operation.

§

Aborted

🔬This is a nightly-only experimental API. (mpmc_channel #126840)

The attempt to block the current thread has been aborted.

§

Disconnected

🔬This is a nightly-only experimental API. (mpmc_channel #126840)

An operation became ready because a channel is disconnected.

§

Operation(Operation)

🔬This is a nightly-only experimental API. (mpmc_channel #126840)

An operation became ready because a message can be sent or received.
