Enum TryRecvError

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

Available on crate feature sync only.

An error returned from the try_recv function on a Receiver.

Variants

Empty

The channel is currently empty. There are still active Sender handles, so data may yet become available.

Closed

There are no more active senders implying no further messages will ever be sent.

Lagged(u64)

The receiver lagged too far behind and has been forcibly disconnected. Attempting to receive again will return the oldest message still retained by the channel.

Includes the number of skipped 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
