Module auth 

Authentication middleware for the proxy.

Supports two modes:

• Simple mode: a single proxy_api_key or proxy_token.
• Role mapping mode: multiple keys, each mapped to an agent role.

The role (if any) is injected into the request extensions as AgentRole before the request reaches the handler.

Structs

AgentRole

Wrapper type stored in request extensions to carry the authenticated role.

AuthState

Auth configuration extracted from ProxyConfig.

Functions

auth_middleware

Axum middleware that authenticates every request.

extract_api_key

Extracts the API key from request headers.
