Struct OptionsCacheLayer 

pub struct OptionsCacheLayer { /* private fields */ }

Available on crate features icap and std only.

Adds bounded, per-service OPTIONS caching to a discovery service.

Refreshes are single-flight per URI, offer set, and explicit cache partition. Cancellation publishes no state, and invalidation fences older in-flight responses.
