Errors from Layer 4 transport operations.

Variants

NotImplemented(String)

The requested transport or feature is not implemented.

ConnectFailed(String)

Failed to connect to the peer.

ListenFailed(String)

Failed to start listening.

HandshakeFailed(String)

The transport-level handshake failed.

VersionMismatch

Protocol version mismatch between peers.

Fields

local: u32

Local protocol version.

remote: u32

Remote protocol version.

HelloTimeout

The remote peer did not produce a hello envelope within the timeout (RFC 017 §8).

HelloMalformed(String)

The remote peer sent a hello envelope that did not parse as a valid HelloEnvelope, or used a version we do not support (RFC 017 §8, close code 4002).

AppMismatch

The remote peer advertised a different app_id in its hello envelope than we did (RFC 017 §8, close code 4001).

Fields

local: String

Our local app_id.

remote: String

The app_id advertised by the remote peer.

ConnectionClosed(String)

The connection was closed unexpectedly.

Timeout(String)

A send or receive operation timed out.

HeartbeatTimeout(Duration)

Heartbeat (ping/pong) failure — the peer stopped responding.

WebSocket(String)

WebSocket protocol error.

Io(Error)

I/O error from the underlying stream.

Serialize(String)

Serialization/deserialization error (e.g., handshake JSON).

Network(NetworkError)

Error from Layer 3 (network).

Trait Implementations

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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.
