Struct crossbeam_channel::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.

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: Copy> Copy for SendError<T>

impl<T> Debug 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 description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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

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

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

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

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

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

Performs the conversion.

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

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

Performs the conversion.

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

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

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

fn ne(&self, other: &SendError<T>) -> bool

This method tests for !=.
