### Other members

- [`await_stage`](/en/ocaml/latest/reference/libtmux_eio-operation-await_stage/) (function): Wait for the named stage or a terminal state. Acknowledgement does not establish completion. Cancelling this observer leaves the operation alone.
- [`cancel`](/en/ocaml/latest/reference/libtmux_eio-operation-cancel/) (function): Remove unsent work. A written request remains owned and drained by the client.
- [`cleanup_receipt`](/en/ocaml/latest/reference/libtmux_eio-operation-cleanup_receipt/) (struct): `created` retains IDs reported before a later hook or completion failure. It does not prove those resources still exist or authorize retry. When the daemon watcher retires an in-flight operation, `cause` retains {!Libtmux.Error.Disconnected}. Idle-reader failures also retain their library cause instead of becoming an explicit client-close reason.
- [`id`](/en/ocaml/latest/reference/libtmux_eio-operation-id/) (function)
- [`inspect`](/en/ocaml/latest/reference/libtmux_eio-operation-inspect/) (function): Read without I/O, including after client closure. Owning domain only.
- [`state`](/en/ocaml/latest/reference/libtmux_eio-operation-state/) (enum)
- [`t`](/en/ocaml/latest/reference/libtmux_eio-operation-t/) (typealias)
