Struct Health 

pub struct Health { /* private fields */ }

Shared readiness flag, flipped on once the process is wired up and flipped off as shutdown begins.

Implementations

impl Health

pub fn new() -> Self

A fresh, not-yet-ready health handle.

pub fn set_ready(&self, ready: bool)

Set readiness; /readyz returns 200 only while true AND the process is not draining (see Health::is_draining).

pub fn with_on_drain(self, hook: Arc<dyn Fn() + Send + Sync>) -> Self

Install a hook /drain fires once, the first time it’s hit — never on a repeat call, so a lifecycle-hook retry or a human re-curling /drain doesn’t repeat binary-specific side effects (e.g. don’t flip a gRPC health check twice). Builder-style.

pub const fn with_drain_propagation_delay(self, delay: Duration) -> Self

Override the delay drain sleeps before responding (production default: DEFAULT_DRAIN_PROPAGATION_DELAY, 5s). Tests set this to Duration::ZERO to keep the delay out of the critical path. Builder-style.

pub fn is_draining(&self) -> bool

true once /drain has been hit at least once.
