Enum std::sync::mpsc::TryRecvError

pub enum TryRecvError {
    Empty,
    Disconnected,
}

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 channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.

Disconnected

The channel's sending half has become disconnected, and there will never be any more data received on it.

Trait Implementations

impl Error for TryRecvError

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace #53487)

Returns a stack backtrace, if available, of where this error ocurred.

impl From<RecvError> for TryRecvError

fn from(err: RecvError) -> TryRecvError

Performs the conversion.
