Enum ResidentKeyRequirement 

pub enum ResidentKeyRequirement {
    Discouraged,
    Preferred,
    Required,
}

Whether the authenticator should store the credential itself.

A resident (discoverable) credential can be picked from a list without the user typing a username first; otherwise the server must name the credential up front. Storage on the authenticator is limited, hence the choice.

Variants

Discouraged

Do not create a resident credential.

Preferred

Create one if possible.

Required

Fail registration if one cannot be created.
