Struct SendError

pub struct SendError<T>(pub T);

An error returned from the send method.

The message could not be sent because the channel is disconnected.

The error contains the message so it can be recovered.

Tuple Fields

0: T

Implementations

impl<T> SendError<T>

pub fn into_inner(self) -> T

Unwraps the message.

Examples

use crossbeam_channel::unbounded;

let (s, r) = unbounded();
drop(r);

if let Err(err) = s.send("foo") {
    assert_eq!(err.into_inner(), "foo");
}

Trait Implementations

impl<T: Clone> Clone for SendError<T>

fn clone(&self) -> SendError<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for SendError<T>

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

Formats the value using the given formatter.

impl<T> Display for SendError<T>

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

Formats the value using the given formatter.

impl<T: Send> Error for SendError<T>

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<T> From<SendError<T>> for SendTimeoutError<T>

fn from(err: SendError<T>) -> SendTimeoutError<T>

Converts to this type from the input type.

impl<T> From<SendError<T>> for TrySendError<T>

fn from(err: SendError<T>) -> TrySendError<T>

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for SendError<T>

fn eq(&self, other: &SendError<T>) -> 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.

impl<T: Copy> Copy for SendError<T>

impl<T: Eq> Eq for SendError<T>

impl<T> StructuralPartialEq for SendError<T>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
