Struct ClusterLifecycleTracker 

pub struct ClusterLifecycleTracker { /* private fields */ }

Thread-safe container for the current ClusterLifecycleState.

Wraps Arc<RwLock<...>> so a single tracker can be shared between start_cluster, the main binary, and HTTP / metrics readers without any cloning beyond the cheap Arc bump.

Every transition method:

1. Takes the write lock.
2. Swaps the stored state.
3. Drops the lock.
4. Emits an info! event with prev, new, and any relevant context fields.
5. Calls readiness::notify_status(...) so systemctl status shows the new phase without any polling.

Implementations

impl ClusterLifecycleTracker

pub fn new() -> Self

Create a fresh tracker in Starting state.

pub fn current(&self) -> ClusterLifecycleState

Read the current state. Returns a clone — callers never hold the lock across an await or a long loop.

pub fn is_ready(&self) -> bool

true iff the tracker has reached Ready.

pub fn to_restarting(&self)

pub fn to_bootstrapping(&self)

pub fn to_joining(&self, attempt: u32)

pub fn to_ready(&self, nodes: usize)

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