Struct VerifiedPrincipal 

Source 
pub struct VerifiedPrincipal(pub String);
Expand description

A caller identity an upstream layer has actually verified.

Insert it as a request extension from a layer that runs before super::RateLimitLayer and has validated the credential (signature, introspection, mTLS, session lookup). When present, the default key function keys on it directly and applies no bucket budget: a verified principal is not caller-mintable, so its cardinality is bounded by however many principals actually exist.

This is opt-in rather than the default because in this framework authentication runs inside the generated handlers — after this layer. Making verified identity mandatory would collapse every existing consumer’s authenticated traffic onto the peer address overnight.

The inner value is hashed before it becomes a bucket key, so a principal id is never written to a store key or a log line verbatim.
