Enum TryRecvError

pub enum TryRecvError {
    Empty,
    Disconnected,
}

🔬This is a nightly-only experimental API. (mpmc_channel)

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 is a nightly-only experimental API. (mpmc_channel)

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

Disconnected

🔬This is a nightly-only experimental API. (mpmc_channel)

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 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<(), 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 description(&self) -> &str

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

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

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

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.
