Struct BiometricPrompt 

Source 
#[repr(C)]
pub struct BiometricPrompt {
    pub reason: AzString,
    pub cancel_label: AzString,
    pub allow_device_credential: bool,
}
Expand description

Configuration for one biometric-auth request — what the OS prompt shows and which fallbacks are allowed. Passed to App::request_biometric_auth.

Strings are plain AzString; an empty string means “use the platform default label” (so callers only override what they care about). This keeps the public surface engine-agnostic and codegen stays a single struct with no nested Option<String> wrappers.

Fields§

§reason: AzString

Reason shown in the OS prompt — required on iOS (localizedReason; the NSFaceIDUsageDescription plist key is declared separately), shown as the Android subtitle and the Windows / Linux message line. Empty is accepted but discouraged.

§cancel_label: AzString

Label for the cancel / negative button (Android requires one; iOS localizedCancelTitle). Empty → platform default (“Cancel”).

§allow_device_credential: bool

Allow the OS passcode / PIN / device-credential fallback when biometrics fail or aren’t enrolled. When the user takes that path the result is BiometricResult::FellBackToPasscode. false = biometric-only (iOS …WithBiometrics, Android BIOMETRIC_STRONG without DEVICE_CREDENTIAL).

Implementations§

impl BiometricPrompt

Source

pub fn new(reason: AzString) -> BiometricPrompt
