Struct std::sync::mpsc::RecvError

1.0.0 · source · [−]

pub struct RecvError;

Expand description

An error returned from the recv function on a Receiver.

The recv operation can only fail if the sending half of a channel (or sync_channel) is disconnected, implying that no further messages will ever be received.

impl From<RecvError> for RecvTimeoutError

source

fn from(err: RecvError) -> RecvTimeoutError

Converts a RecvError into a RecvTimeoutError.

This conversion always returns RecvTimeoutError::Disconnected.

No data is allocated on the heap.
