Errors raised by the Derive WebSocket client.

Variants

Transport(String)

Transport-level failure (handshake, send, broken pipe).

Serde(Error)

JSON (de)serialization failed for an outbound or inbound frame.

JsonRpc

JSON-RPC error envelope returned by the venue.

Fields

code: i64

Venue-defined error code.

message: String

Human-readable error message.

data: Option<Value>

Optional structured diagnostic payload.

RequestCancelled

Awaited request response was not delivered (handler dropped the sender).

Fields

method: String

Method that was awaiting a response.

Timeout

No response arrived within the configured request timeout. The request was sent, so the outcome of a state-changing write is unknown.

Fields

method: String

Method that was awaiting a response.

Auth(AuthError)

Auth header construction failed (e.g. clock skew, signer error).

MissingCredentials

Private operation invoked without credentials configured on the client.

Fields

operation: String

Operation that requires authentication.

NotConnected

Client used before connect() completed.

Implementations

impl DeriveWsError

pub fn transport(msg: impl Into<String>) -> Self

Trait Implementations

impl Debug for DeriveWsError

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

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
