Enum TrySendError 

pub enum TrySendError<T> {
    Full(T),
    Disconnected(T),
}

This enumeration is the list of the possible error outcomes for the try_send method.

Variants

Full(T)

The data could not be sent on the channel because it would require that the callee block to send the data.

If this is a zero-capacity channel, then the error indicates that there was no receiver available to receive the message at the time.

Disconnected(T)

This channel’s receiving half has disconnected, so the data could not be sent. The data is returned back to the callee in this case.

Implementations

impl<T> TrySendError<T>

pub fn into_inner(self) -> T

Unwraps the value.

Examples

use crossbeam_channel::bounded;

let (tx, rx) = bounded(0);

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

Trait Implementations

impl<T> Clone for TrySendError<T>

where T: Clone,

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for TrySendError<T>

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

Formats the value using the given formatter.

impl<T> Display for TrySendError<T>

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

Formats the value using the given formatter.

impl<T> Error for TrySendError<T>

where T: Send,

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

Returns the lower-level source of this error, if any.

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 TrySendError<T>

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

Converts to this type from the input type.

impl<T> PartialEq for TrySendError<T>

where T: PartialEq,

fn eq(&self, other: &TrySendError<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 for TrySendError<T>

where T: Copy,

impl<T> Eq for TrySendError<T>

where T: Eq,
