Enum 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 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<(), Error>

Formats the value using the given formatter.

impl Display for TryRecvError

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

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) -> TryRecvError

Converts a RecvError into a TryRecvError.

This conversion always returns TryRecvError::Disconnected.

No data is allocated on the heap.

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.
