Enum Biometry 

pub enum Biometry {
    None,
    Fingerprint,
    Face,
    Iris,
    Unknown,
}

The kind of biometric sensor the device offers for app prompts.

Variants

None

No biometric sensor: a prompt can still succeed with the device credential.

Fingerprint

A fingerprint reader (Touch ID, Android fingerprint, a Windows Hello fingerprint reader).

Face

Face recognition (Face ID, Android face unlock, Windows Hello face).

Iris

An iris scanner (Android).

Unknown

A sensor the platform has but does not describe to apps, or several kinds at once. Windows Hello never says which credential a person set up; Apple’s Optic ID reports here.
