pub enum TryRecvError {
Empty,
Disconnected,
}
🔬This is a nightly-only experimental API. (
mpmc_channel
)Expand description
This enumeration is the list of the possible reasons that try_recv
could
not return data when called. This can occur with both a channel
and
a sync_channel
.
Variants§
Empty
🔬This is a nightly-only experimental API. (
mpmc_channel
)This channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.
Disconnected
🔬This is a nightly-only experimental API. (
mpmc_channel
)The channel’s sending half has become disconnected, and there will never be any more data received on it.
