Enum MuxError 

pub enum MuxError {
    Framing(FramingError),
    MalformedProbe(EndpointProbeServerError),
    UnexpectedFirstPartyFrame {
        payload_protocol: u32,
    },
    UnservedPayloadProtocol {
        payload_protocol: u32,
    },
}

Errors surfaced by BackendEndpointMux::poll.

All of them mean the connection is in an unknown state; the daemon should drop it (matching broker behavior for framing violations).

Variants

Framing(FramingError)

Outer framing violation (oversize body, undecodable frame).

MalformedProbe(EndpointProbeServerError)

A frame with the probe payload protocol failed probe validation.

UnexpectedFirstPartyFrame

A frame carried a first-party payload protocol this endpoint does not serve (e.g. broker Hello sent to a backend daemon).

Fields

payload_protocol: u32

The first-party payload protocol the peer used.

UnservedPayloadProtocol

A frame carried a payload protocol other than the ones this mux was configured to accept.

Fields

payload_protocol: u32

The payload protocol the peer used.

Trait Implementations

impl Debug for MuxError

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

Formats the value using the given formatter.

impl Display for MuxError

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

impl Error for MuxError

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.
