Implementations

impl HealthChecker

pub fn new() -> Arc<HealthChecker>

pub fn register(&self, check: HealthCheck)

Register a health check.

pub fn register_liveness<F, Fut>(&self, name: impl Into<String>, check_fn: F)

where F: Fn() -> Fut + Send + Sync + 'static, Fut: Future<Output = bool> + Send + 'static,

Register a simple liveness check.
