Enum DeriveError 

pub enum DeriveError {
    Http(DeriveHttpError),
    WebSocket(DeriveWsError),
    Auth(AuthError),
    Config(String),
}

Unified error type aggregating the Derive adapter’s component errors.

Variants

Http(DeriveHttpError)

HTTP transport, JSON-RPC, or credential errors raised by DeriveHttpError.

WebSocket(DeriveWsError)

WebSocket transport, framing, or login errors raised by DeriveWsError.

Auth(AuthError)

Signing or session authentication errors.

Config(String)

Configuration error surfaced during client construction (placeholder constants, invalid hex, missing credentials).

Implementations

impl DeriveError

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

Constructs a DeriveError::Config error.

pub fn is_retryable(&self) -> bool

Returns true for errors that did not reach the venue and can safely be retried (transport, timeout, gateway 5xx).

pub fn is_fatal(&self) -> bool

Returns true for errors that indicate a fatal session state (deregistered session key, subaccount withdrawn, compliance halt). Fatal errors require operator intervention and must not be retried.

Trait Implementations

impl Debug for DeriveError

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

Formats the value using the given formatter.

impl Display for DeriveError

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

Formats the value using the given formatter.

impl Error for DeriveError

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.
