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
EmptyThis channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.
DisconnectedThe channel’s sending half has become disconnected, and there will never be any more data received on it.
Trait Implementations
impl Clone for TryRecvErrorfn 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 TryRecvErrorfn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Display for TryRecvErrorfn fmt(&self, f: &mut Formatter<'_>) -> Result
Formats the value using the given formatter. Read more
impl Error for TryRecvErrorfn description(&self) -> &str👎Deprecated since 1.42.0: 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 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 #99301)
Provides type based access to context intended for error reports. Read more
impl From<RecvError> for TryRecvErrorfn from(err: RecvError) -> TryRecvErrorConverts a RecvError into a TryRecvError.
This conversion always returns TryRecvError::Disconnected.
No data is allocated on the heap.
impl PartialEq for TryRecvErrorfn 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.
