Struct libfprint_rs::FpContext

pub struct FpContext { /* private fields */ }

This struct allows you to discover fingerprint scanning hardware. This is the starting point when integrating libfprint-rs into your software.

Implementations

impl FpContext

pub fn new() -> FpContext

Create a new FpContext

Examples:

use libfprint_rs::FpContext;

let context = FpContext::new();

examples/verify.rs (line 6)

fn main() {
    let context = FpContext::new();
    let devices = context.get_devices();

    let dev = match devices.iter().next() {
        Some(dev) => dev,
        None => {
            eprintln!("No devices detected.");
            std::process::exit(1);
        }
    };
    let print_matched = verify(dev).unwrap();

    if print_matched {
        println!("Print matched");
    } else {
        println!("Prints don't match!!");
    }

            std::process::exit(1);
        }

    let print = enroll(dev);
    if let Ok(print) = print {
        let username = print.get_username().unwrap();
        println!("User provided username: \"{}\"", username);
    }
}

pub fn enumerate(&self)

Enumerate all the devices connected to the system

This function will enumerate all the devices connected to the system and add them to the context.

pub fn get_devices<'a>(&'a self) -> DeviceList<'a>

Get the list of devices connected to the system

Examples:

use libfprint_rs::FpContext;

let context = FpContext::new();
let devices = context.get_devices();
