Struct Lifecycle 

pub struct Lifecycle { /* private fields */ }

Lifecycle state wrapper held in RuntimeInner.

Implementations

impl Lifecycle

pub fn new() -> Lifecycle

pub fn mark_restore_started(&self)

PLAN.md Phase 9.1 — mark a cold-start phase boundary. Boot code calls these as it transitions through restore-from- remote, WAL replay, and index warmup. Idempotent: only the first call sets the timestamp; subsequent calls are no-ops so a retried boot doesn’t reset the gauge.

pub fn mark_restore_ready(&self)

pub fn mark_wal_replay_started(&self)

pub fn mark_wal_replay_ready(&self)

pub fn mark_index_warmup_started(&self)

pub fn mark_index_warmup_ready(&self)

pub fn set_restore_started_at_ms(&self, ms: u64)

PLAN.md Phase 9.1 — backfill phase markers with an explicit timestamp. Used when the runtime captures the wall-clock before Lifecycle is constructible (e.g. before storage open) and wants to replay it into the markers afterwards. Idempotent (only sets when current value is 0).

pub fn set_restore_ready_at_ms(&self, ms: u64)

pub fn set_wal_replay_started_at_ms(&self, ms: u64)

pub fn set_wal_replay_ready_at_ms(&self, ms: u64)

pub fn cold_start_phases(&self) -> ColdStartPhases

Snapshot every cold-start marker in one read. Callers compute per-phase deltas via ColdStartPhases::durations_ms().

pub fn phase(&self) -> Phase

pub fn started_at_ms(&self) -> u64

pub fn ready_at_ms(&self) -> Option<u64>

pub fn not_ready_reason(&self) -> Option<String>

pub fn shutdown_report(&self) -> Option<ShutdownReport>

pub fn set_starting_reason(&self, reason: impl Into<String>)

Mark a transient “still starting, here’s why” reason. Called from boot stages so /health/ready 503 carries operator-useful context (e.g. “wal_replay”, “restore_from_remote”, “initial_checkpoint”).

pub fn mark_ready(&self) -> bool

Transition Starting → Ready. Idempotent: a second call leaves the existing ready_at_ms untouched. Returns true if this call effected the transition.

pub fn mark_draining(&self)

Transition Ready → Draining (best effort — already-Stopped runtimes stay Stopped). Idempotent.

pub fn begin_shutdown(&self) -> bool

Transition into ShuttingDown if not already past it. Returns true if this call started the shutdown (caller should run the actual flush pipeline); false if shutdown was already started or finished by someone else (caller should poll for the existing report instead).

pub fn finish_shutdown(&self, report: ShutdownReport)

Stamp the final report and move to Stopped. Called by Engine::graceful_shutdown after the flush pipeline finishes.
