Enum TryRecvError 

pub enum TryRecvError<T> {
    Empty(Receiver<T>),
    Disconnected,
}

🔬This is a nightly-only experimental API. (oneshot_channel #143674)

An error returned from the try_recv method.

See the documentation for try_recv for more information on how to use this error.

Variants

Empty(Receiver<T>)

🔬This is a nightly-only experimental API. (oneshot_channel #143674)

The Sender has not sent a message yet, but it might in the future (as it has not yet disconnected). This variant contains the Receiver that try_recv took ownership over.

Disconnected

🔬This is a nightly-only experimental API. (oneshot_channel #143674)

The corresponding Sender half of this channel has become disconnected, and there will never be any more data sent over the channel.

Trait Implementations

impl<T> Debug for TryRecvError<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Display for TryRecvError<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl<T> Error for TryRecvError<T>

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access #99301)

Provides type-based access to context intended for error reports.

impl<T> From<RecvError> for TryRecvError<T>

fn from(err: RecvError) -> TryRecvError<T>

Converts a RecvError into a TryRecvError.

This conversion always returns TryRecvError::Disconnected.
