Enum LifecycleState 

pub enum LifecycleState {
    Opening,
    Open,
    Draining,
    Closing,
    Closed,
    Poisoned,
}

Lifecycle states of one storage core (spec §10.1, S1A-004).

Variants

Opening

Recovery, WAL opening, open-generation advancement, and table mounting are in progress. No operations are admitted.

Open

The core admits operations.

Draining

shutdown() has begun: new sessions and writes are rejected while in-flight operations drain.

Closing

Operations have drained; durable state is being synced, workers are stopping, and the file lock is being released.

Closed

The core is fully shut down. Every operation fails.

Poisoned

An unrecoverable internal error (e.g. a durability poison) left the core unable to continue. Every operation fails.
