    Zmq(ZmqError),
    Wire(Error),
    HandshakeTimeout {
        stage: &'static str,
        pending: Vec<u16>,
        timeout: Duration,
    },

        timeout: Duration,
    },
    Unavailable(StreamError),
}

An error from connecting to the engines or submitting a request.

Variants

Zmq(ZmqError)

A socket operation failed.

Wire(Error)

A message did not match the wire schema.

HandshakeTimeout

Not every engine finished a handshake stage in time.

Fields

stage: &'static str

The stage that did not complete.

pending: Vec<u16>

Engine indices that had not completed it.

timeout: Duration

The configured handshake timeout.

Handshake(String)

An engine broke the handshake protocol.

InvalidRequest(String)

The request cannot be submitted as given.

DuplicateRequestId(String)

A request with this id is already in flight.

SendTimeout

The engine did not accept the message in time.

Fields

engine_index: u16

The engine the message was for.

timeout: Duration

The configured send timeout.

Unavailable(StreamError)

The engines are gone; see StreamError for why.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ZmqError> for Error

fn from(source: ZmqError) -> Self

Converts to this type from the input type.
