Crate libdrmtap 

libdrmtap

Safe Rust wrapper around the libdrmtap C library for DRM/KMS screen capture.

Example

use libdrmtap::DrmTap;

let mut tap = DrmTap::open(None).expect("Failed to open DRM device");

// List displays
let displays = tap.list_displays().unwrap();
for d in &displays {
    println!("{}: {}x{}", d.name, d.width, d.height);
}

// Capture a frame
let frame = tap.grab_mapped().expect("Capture failed");
println!("{}x{} stride={}", frame.width(), frame.height(), frame.stride());

// Access pixel data as a byte slice
if let Some(pixels) = frame.data() {
    println!("First pixel: {:02x}{:02x}{:02x}",
             pixels[2], pixels[1], pixels[0]); // RGB from XRGB
}
