localauthentication-rs

localauthentication-rs provides a wrapper for LAContext in Apple's LocalAuthentication framework.

Warning This is still in development! There may be breaking changes in the future.

This crate can be used to verify a user's identity in macOS (or iOS), being able to choose how via the LAPolicy enumeration:

• DeviceOwnerAuthenticationWithBiometrics: User authentication with biometry.
• DeviceOwnerAuthentication: User authentication with Apple Watch, biometry, or the device passcode.
• DeviceOwnerAuthenticationWithWatch: User authentication with Apple Watch.
• DeviceOwnerAuthenticationWithBiometricsOrWatch: User authentication with either biometry or Apple Watch.

In the example below, we attempt to authenticate with the user via their biometrics (Touch ID or Face ID), Apple Watch, or in the "worst case scenario", their account password:

```rs use localauthentication_rs::{LAPolicy, LocalAuthentication};

fn main() { // Create a new instance of LocalAuthentication let local_authentication = LocalAuthentication::new();

// Try to authenticate the user
let authenticated = local_authentication.evaluate_policy(
    LAPolicy::DeviceOwnerAuthenticationWithBiometrics,
    "authenticate your user",
);

// Print the result
if authenticated {
    println!("Welcome!");
} else {
    println!("Not authenticated...");
}

} ```
