Struct NodeStatus 

pub struct NodeStatus {
    pub view: u64,
    pub primary: bool,
    pub ready: bool,
    pub stopped: bool,
    pub epoch: u64,
    pub retired: bool,
    pub joining: bool,
    pub op: Op,
    pub checkpoint: Op,
    pub commit: Op,
    pub applied: Op,
}

A replica’s role and progress. Status receivers are notified when view, primary, ready or stopped changes; the progress fields are updated in place on every commit without waking anyone, so read them by polling.

Fields

view: u64

primary: bool

ready: bool

Primary, with every entry committed and applied: the engine may open.

stopped: bool

The replica stopped after an unrecoverable storage error.

epoch: u64

The membership epoch this replica is in (see ReplicaNode::membership).

retired: bool

A membership change removed this replica: it takes part in nothing and can be stopped once the new members have caught up.

joining: bool

A new member that has not yet learned the membership including it.

op: Op

checkpoint: Op

Committed prefix covered by a durable portable checkpoint.

commit: Op

applied: Op
