Type Alias RingProvider 

pub type RingProvider = Arc<dyn Fn() -> RingSnapshot + Send + Sync>;

Type alias for a closure that produces a fresh RingSnapshot every time the /ring route is hit.

The closure must be Send + Sync so a clone can be moved into each accept-handler task. Embedders set it via StatsServer::with_ring_provider; when unset the /ring route returns 503 Service Unavailable.

Aliased Type

pub struct RingProvider { /* private fields */ }
