Enum SendError 

pub enum SendError {
    ReceiverClosed,
    MaxMessageSizeExceeded,
    Io(Error),
}

Error when sending a oneshot or mpsc message. For local communication, the only thing that can go wrong is that the receiver has been dropped.

For rpc communication, there can be any number of errors, so this is a generic io error.

Variants

ReceiverClosed

The receiver has been closed. This is the only error that can occur for local communication.

MaxMessageSizeExceeded

The message exceeded the maximum allowed message size (see MAX_MESSAGE_SIZE).

Io(Error)

The underlying io error. This can occur for remote communication, due to a network error or serialization error.

Trait Implementations

impl Debug for SendError

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

Formats the value using the given formatter.

impl Display for SendError

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

Formats the value using the given formatter.

impl Error for SendError

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.
