A premium, high-performance Wayland screen locker written in Rust, designed to replicate and exceed the capabilities of swaylock-effects while ensuring stability on modern compositors like Niri and Sway.

Features

Blazing Fast Performance: Written in 100% safe Rust for maximum efficiency and security.
Advanced Visual Effects:
- Gaussian Blur: Highly optimized blur effect for your desktop background.
- Vignette: Add a professional vignette effect to darken the edges of your screen.
- Fade-in Animation: Smooth transition from your desktop to the lock screen.
Iconic swaylock-effects UI:
- Dynamic Rotating Highlights: Premium visual feedback as you type, with segments that appear at random angles and rotate dynamically.
- Internal Information Hub: A perfectly centered clock, date, and system uptime indicator inside the ring.
- Custom Colors: Full control over ring, inside, separator, and highlight colors.
Robust Logic:
- Niri Compatibility: Fixed protocol violations that cause red screens on Niri.
- Pre-lock Screenshot: Captures your desktop before locking to ensure visual effects work perfectly even if the compositor hides surfaces immediately.
- Grace Period: Configurable unlock grace period for convenience.
- Safe Exit: Always waits for the compositor's confirmation before exiting, preventing session corruption.
Permanent Logging: Verbose debug logs are always captured in ~/.wayrustlock.log for immediate troubleshooting.
