Enum CredentialKind 

pub enum CredentialKind {
    None,
    Token,
    User,
}

Which shape of credential a CredentialProbe holds.

Variants

None

Token

User

A named user — and, when the connection presenting it is live, positive proof that the broker is running users rather than a token: nats-server refuses to load a config carrying both a token and a users array (“Can not have a token and a users array”) and rejects token authentication outright once users are defined.

That proof is the only thing that makes a reported authorized_user safe to record verbatim. Note what is not proof: holding no credential locally. A process that never authenticated at all can still read a monitoring endpoint, and inferring the broker’s mode from a local absence would let a misconfigured host store the very secret the rest of this type exists to protect.
