Enum AuthOutcome 

pub enum AuthOutcome {
    Authenticated(Box<AdminUser>),
    UnknownUser,
    WrongPassword(Box<AdminUser>),
    Disabled(Box<AdminUser>),
}

The result of checking a username and password.

Every variant but AuthOutcome::Authenticated must be reported to the client identically – one invalid_credentials, never “no such user” – but they are kept apart here so the log can say which happened. A caller that collapses them into the response and not into the log is doing the right thing with both.

Variants

Authenticated(Box<AdminUser>)

Password verified and the account is usable.

UnknownUser

No such username. The KDF ran anyway – see authenticate.

WrongPassword(Box<AdminUser>)

The username exists; the password did not match.

Disabled(Box<AdminUser>)

The password was right, but the account is disabled.
