Struct SupervisionPolicy

pub struct SupervisionPolicy {
    pub restart_backoff_initial: Duration,
    pub restart_backoff_max: Duration,
    pub restart_backoff_multiplier: NonZeroU32,
    pub restart_window: Duration,
    pub max_restarts_per_window: NonZeroU32,
    pub stop_grace: Duration,
}

Expand description

The operator-configured restart discipline for managed workers.

Fields§

§restart_backoff_initial: Duration

Delay before the FIRST restart in a window.

§restart_backoff_max: Duration

Ceiling the geometric backoff is clamped to.

§restart_backoff_multiplier: NonZeroU32

Geometric growth factor applied per restart already made in the window.

§restart_window: Duration

Sliding window over which restarts are counted.

§max_restarts_per_window: NonZeroU32

Restarts permitted within one window before the instance is failed.

§stop_grace: Duration

Grace given to each of SIGTERM and SIGKILL when stopping a group.

Implementations§

impl SupervisionPolicy

pub fn backoff_after(&self, restarts_in_window: u32) -> Duration

The delay owed before a restart, given how many restarts already happened inside the current window.

restarts_in_window counts the restarts already made, so the first restart of a window (0 prior) waits exactly restart_backoff_initial. Growth is geometric and saturating, and the result is always clamped to restart_backoff_max.
