Rust library for the GT-521F52, GT-521F32, and GT-511C3(R) fingerprint scanners.

It uses nusb under the hood.

• Support for the most of the GT-521F52 API
• SCSI-over-USB; no adapter required

use gt5::autodiscover;

#[tokio::main]
async fn main() {
    let gt5 = autodiscover().await.expect("Could not get gt5");

    match gt5.get_enroll_count().await {
        Ok(count) => println!("Enrolled count: {count}"),
        Err(err) => eprintln!("Could not get enrolled count: {err}"),
    }
}

See examples/ for more examples.

• You are unable to run this on MacOSX, as you are unable to claim the USB device. This is a limitation of the nusb library.
