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 TryRecvError

1.24.0 · source

fn from(err: RecvError) -> TryRecvError

source

Converts a RecvError into a TryRecvError.

This conversion always returns TryRecvError::Disconnected.

No data is allocated on the heap.

1.24.0 · source

fn from(err: RecvError) -> RecvTimeoutError

source

Converts a RecvError into a RecvTimeoutError.

This conversion always returns RecvTimeoutError::Disconnected.

No data is allocated on the heap.

impl PartialEq<RecvError> for RecvError

source

fn eq(&self, other: &RecvError) -> bool

source

This method tests for self and other values to be equal, and is used by ==. Read more

fn ne(&self, other: &Rhs) -> bool
