Enum ProtocolError 

pub enum ProtocolError {
    Frame(FrameError),
    UnsupportedCommand(i32),
    InvariantViolation(&'static str),
    Handshake(&'static str),
    Server {
        code: i32,
        message: String,
    },
}

Errors that the Connection state machine can surface.

Variants

Frame(FrameError)

Frame decoding failed.

UnsupportedCommand(i32)

The remote sent a BaseCommand whose type did not match any populated oneof field.

InvariantViolation(&'static str)

The remote sent a command that violates the local state machine invariants (e.g. a SendReceipt referencing an unknown producer).

Handshake(&'static str)

The handshake was attempted while the connection was not in a state that supports it.

Server

The peer signalled a fatal error via CommandError or CommandSendError.

Fields

code: i32

Pulsar wire-protocol ServerError code (raw i32 — translate via pb::ServerError::try_from).

message: String

Human-readable broker message.

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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<FrameError> for ProtocolError

fn from(source: FrameError) -> ProtocolError

Converts to this type from the input type.
