Struct AltSvcLayer 

pub struct AltSvcLayer { /* private fields */ }

Available on crate features http and std only.

Observe alternative services on an HTTP request service.

Configure once with a shared cache. Every call resolves its own logical origin and reads the actual connection’s EstablishedHttpService and authentication metadata. A selector may supply HttpServiceSelection on the request; no particular selector implementation is required.

HTTPS advertisements can update shared discovery only when the connection authenticated this origin under ConnectionPolicyScope::Connector. Request-specific trust never changes the configured cache or other requests’ discovery state. Plaintext advertisements remain hints (RFC 8164).

Remote failures are recognized as ConnectionError, directly or inside BoxError. Other error types pass through without changing shared backoff; custom services can box classified source chains to participate.
