Enum SendError 

pub enum SendError {
    ContextTerminated,
    HostUnreachable,
    InvalidMessage,
    Interrupted,
    Unexpected(Error),
}

The type of errors that can occur when sending a ØMQ message.

The following ØMQ error codes may occur in the underlying ØMQ implementation, but do not need to be handled by users of this crate:

• EAGAIN - this crate will automatically retry if this error code is produced
• ENOTSUP - unsupported operations are prevented by the design of this crate
• EINVAL - multipart messages are not yet supported
• ENOTSOCK - the design of this crate prevents sending messages on an invalid socket
• EFSM - this applies only to REP/REQ sockets which have their own error type

Variants

ContextTerminated

The ØMQ context associated with the specified socket was terminated.

Note that this error cannot occur unless you access the raw socket using as_raw_socket().

Corresponds to ØMQ error code ETERM

HostUnreachable

The host is unreachable and the message cannot be routed.

Corresponds to ØMQ error code EHOSTUNREACH.

InvalidMessage

The message is invalid.

Corresponds to ØMQ error code EFAULT.

Interrupted

The operation was interrupted by delivery of a signal before the message was sent.

Corresponds to ØMQ error code EINTR. TODO verify if this can actually occur, or if it can be handled internally with a retry

Unexpected(Error)

ØMQ produced an error variant that is not documented to occur when sending a message. This should never happen and should be treated as a bug.

Trait Implementations

impl Clone for SendError

fn clone(&self) -> SendError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.

impl From<Error> for SendError

fn from(other: Error) -> Self

Converts to this type from the input type.

impl From<SendError> for Error

fn from(other: SendError) -> Self
