Struct Credentials 

pub struct Credentials {
    pub bearer: Option<String>,
    pub client_cert_subject: Option<String>,
}

Raw credentials extracted from a request, before authentication.

Only the bearer token is populated by Credentials::from_metadata today; client_cert_subject is the documented seam for mTLS, which tonic exposes on the request extensions inside the service (not in the interceptor), so a full wiring fills it in there. Keeping both here lets one provider consume either without a second extraction path.

Fields

bearer: Option<String>

Value after Bearer in the authorization metadata, if any.

client_cert_subject: Option<String>

Subject (SAN/CN) of a verified client certificate, if mTLS is in use.
