Enum SignalBridgeError 

pub enum SignalBridgeError {
    UnknownWaitpoint,
    TokenMismatch,
    Backend(SdkError),
}

Error returned by a signal-bridge authentication + dispatch attempt. On success, verify_and_deliver returns the SignalOutcome from the underlying FlowFabricWorker::deliver_signal call; this enum only enumerates the rejection + fault cases.

Variants

UnknownWaitpoint

The waitpoint has no stored token — it was consumed, expired, or never existed. Real bridges typically map this to HTTP 404.

TokenMismatch

The token presented by the external actor did not match the stored token. Real bridges typically map this to HTTP 401.

Backend(SdkError)

Underlying SDK / engine failure (read-waitpoint-token backend error, network fault, deliver-signal rejection).

Trait Implementations

impl Debug for SignalBridgeError

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

Formats the value using the given formatter.

impl Display for SignalBridgeError

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

Formats the value using the given formatter.

impl Error for SignalBridgeError

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<SdkError> for SignalBridgeError

fn from(e: SdkError) -> Self

Converts to this type from the input type.
