Enum RecvError 

pub enum RecvError {
    Closed,
    Lagged(u64),
}

Available on crate feature sync only.

An error returned from the recv function on a Receiver.

Variants

Closed

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

Lagged(u64)

The receiver lagged too far behind: one or more messages were overwritten in the ring buffer before this receiver could read them.

The receiver remains subscribed. Its internal cursor has been advanced to the oldest message still retained by the channel; the next successful recv call returns that message (unless further sends overwrite it first).

The u64 is the number of messages that were skipped (dropped before the receiver’s previous cursor position).

Trait Implementations

impl Clone for RecvError

fn clone(&self) -> RecvError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RecvError

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

Formats the value using the given formatter.

impl Display for RecvError

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

Formats the value using the given formatter.

impl Error for RecvError

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 RecvError

fn eq(&self, other: &RecvError) -> 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.
