Enum TryRecvError

pub enum TryRecvError {
    Overflowed(u64),
    Empty,
    Closed,
}

An error returned from Receiver::try_recv().

Variants

Overflowed(u64)

The channel has overflowed since the last element was seen. Future recv operations will succeed, but some messages have been skipped.

Empty

The channel is empty but not closed.

Closed

The channel is empty and closed.

Implementations

impl TryRecvError

pub fn is_empty(&self) -> bool

Returns true if the channel is empty but not closed.

pub fn is_closed(&self) -> bool

Returns true if the channel is empty and closed.

pub fn is_overflowed(&self) -> bool

Returns true if this error indicates the receiver missed messages.

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

Formats the value using the given formatter.

impl Display for TryRecvError

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

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 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.
