Enum TryRecvError 

pub enum TryRecvError {
    Empty,
    Disconnected,
}

An error that occurs when trying to receive a value from a channel when there are no messages in the channel. If there are no messages in the channel and all senders are dropped, then the Disconnected error will be returned.

Variants

Empty

An error that occurs when trying to receive a value from an empty channel.

Disconnected

The channel has been closed because all senders have been dropped and there are no more messages waiting in the channel.

Trait Implementations

impl Clone for TryRecvError

fn clone(&self) -> TryRecvError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TryRecvError

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

Formats the value using the given formatter.

impl Display for TryRecvError

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

Formats the value using the given formatter.

impl Error for TryRecvError

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)

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

impl From<RecvError> for TryRecvError

fn from(err: RecvError) -> Self

Converts to this type from the input type.

impl PartialEq for TryRecvError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
