Enum sp_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 Eq for TryRecvError

impl Error for TryRecvError

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<RecvError> for TryRecvError

pub 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

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

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

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
