Enum flume::TryRecvError

pub enum TryRecvError {
    Empty,
    Disconnected,
}

An error that may be emitted when attempting to fetch a value on a receiver when there are no messages in the channel. If there are no messages in the channel and all senders are dropped, then TryRecvError::Disconnected will be returned.

Variants

Empty

The channel was empty when the receive was attempted.

Disconnected

All senders were dropped and no messages are waiting in the channel, so no further messages can be received.

Trait Implementations

impl Clone for TryRecvError

fn clone(&self) -> TryRecvError

Returns a copy 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)>

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, demand: &mut Demand<'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<TryRecvError> for TryRecvError

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

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

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

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