Struct fprint_rs::FPrint

pub struct FPrint;

Methods

impl FPrint

pub fn new() -> Result<FPrint>

Initialise libfprint.

To enable debug output of libfprint specifically, use GLib's G_MESSAGES_DEBUG environment variable as explained in Running and debugging GLib Applications.

The log domains used in libfprint are either libfprint or libfprint-FP_COMPONENT where FP_COMPONENT is defined in the source code for each driver, or component of the library. Starting with all and trimming down is advised.

To enable debugging of libusb, for USB-based fingerprint reader drivers, use libusb's LIBUSB_DEBUG environment variable as explained in the libusb-1.0 API Reference.

Example:

# LIBUSB_DEBUG=4 G_MESSAGES_DEBUG=all my-libfprint-application

pub fn discover(&self) -> Result<DiscoveredDevices>

Scans the system and returns a list of discovered devices. This is your entry point into finding a fingerprint reader to operate.
