Failure leaving a conversation (the F-3b R1 explicit-leave surface, wrapping the substrate’s terminal LeaveRequest — brief §Gate fill S1 leave paragraph, probe findings 2026-07-23). The typed already-left answers are OUTCOMES (LeaveOutcome), never errors.

Variants

Refused

The substrate answered the leave with a typed refusal (stale authority, generation conflict, identity refusal — the exact upstream answer is preserved in the detail).

Fields

class: RefusalClass

Refusal class in frame vocabulary.

detail: String

Exact upstream answer.

ConnectionLost

The connection was lost before the leave’s correlated answer.

Fields

detail: String

Exact transport fate.

AnswerTimeout

The declared answer window elapsed without the leave’s correlated terminal answer.

Fields

waited: Duration

Total time waited.

Endpoint

The bus endpoint was rejected or unreachable (the resumed-leave path’s connect leg).

Fields

detail: String

Exact transport-layer detail.

ResumeRejected

The caller-supplied resume state failed decode/validate/restore (the resumed-leave path’s restore leg).

Fields

detail: String

Exact typed decode/restore refusal.

Store

The caller-owned durable store failed a persistence barrier.

Fields

detail: String

Exact store failure.

Protocol

A protocol-shape violation at the leave seam.

Fields

detail: String

Exact violation detail.

Trait Implementations

impl Debug for LeaveError

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

Formats the value using the given formatter.

impl Display for LeaveError

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

Formats the value using the given formatter.

impl Error for LeaveError

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>)
