Enum std::sync::mpsc::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 copy of the value. Read more
fn clone_from(&mut self, source: &Self)
Performs copy-assignment from source
. Read more
impl Debug for TryRecvError
fn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Display for TryRecvError
fn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Error for TryRecvError
fn description(&self) -> &str
use the Display impl or to_string()
fn source(&self) -> Option<&(dyn Error + 'static)>
The lower-level source of this error, if any. Read more
fn backtrace(&self) -> Option<&Backtrace>
Returns a stack backtrace, if available, of where this error occurred. Read more
fn cause(&self) -> Option<&dyn Error>
replaced by Error::source, which can support downcasting
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<TryRecvError> for TryRecvError
fn eq(&self, other: &TryRecvError) -> bool
This method tests for self
and other
values to be equal, and is used by ==
. Read more
fn ne(&self, other: &Rhs) -> bool
This method tests for !=
.
