Enum CancelError 

pub enum CancelError {
    NotFound(SessionId),
}

Error returned by crate::execution::ExecutionService::cancel.

cancel is idempotent for sessions already in a terminal state: calling cancel on a Done, Failed, or already-Cancelled session returns Ok(()). The only error is when the session does not exist at all.

Variants

NotFound(SessionId)

No session with the given id exists in the registry.
