Struct InstanceLife 

pub struct InstanceLife {
    pub state: LifecycleState,
    pub since_ms: u64,
    pub misses: u32,
    pub restarts: Vec<u64>,
    pub last_poll_ms: u64,
}

One instance’s life on one side of the wire.

Fields

state: LifecycleState

Current state.

since_ms: u64

When it entered the state (ms).

misses: u32

Consecutive bad polls.

restarts: Vec<u64>

Times of the restarts still inside the window (ms, ascending).

last_poll_ms: u64

When the last poll happened (ms); 0 before the first.

Implementations

impl InstanceLife

pub fn new(state: LifecycleState, now_ms: u64) -> Self

A new life in state.

pub fn transition( &mut self, to: LifecycleState, now_ms: u64, ) -> Result<LifecycleState, IllegalTransition>

Take a legal step (the miss count resets on entering Running).

pub fn restart_decision( &self, policy: &RestartPolicy, now_ms: u64, ) -> RestartDecision

Whether policy allows a restart at now_ms. Restarts older than the window no longer count. Does not record anything.

pub fn record_restart(&mut self, policy: &RestartPolicy, now_ms: u64)

Record a restart at now_ms (and forget those outside the window).
