Linux Port: Request for meter-core-rs guidance to enable live DPS meter

[multiheros]

Summary

I've been working on a Linux port of LOA Logs and have successfully compiled and run the application on CachyOS (Arch-based, kernel 6.18.13-2-cachyos-lts). The app works perfectly as a log viewer — all UI, database, charts, settings, tray, and log browsing features are fully functional.

However, the live DPS meter (real-time packet capture) is currently unavailable because it depends on meter-core-rs, which is a private repository.

What's been done

The Linux port is available at multiheros/loa-logs (linux-port branch). Here's what was needed to get it compiling and running:

• Disabled meter-core dependency (optional feature, already behind #[cfg(feature = "meter-core")])
• Added #[cfg(target_os = "windows")] guards for window-vibrancy blur/clear (not supported on Linux)
• Fixed dirs::app_data_dir() → dirs::data_dir() for proper XDG path resolution
• Fixed auto-launch linux module (missing anyhow::Result import, &str borrow issue)
• Removed common-controls-v6 feature from rfd (Windows-only)
• Added automatic WebKitGTK Wayland compatibility env vars (WEBKIT_DISABLE_DMABUF_RENDERER, GDK_BACKEND)
• Cleaned up Cargo.lock removing Windows-only transitive dependencies

All changes use conditional compilation (#[cfg(target_os)]), so nothing breaks on Windows.

The blocker: live meter on Linux

The only missing piece is the live DPS meter. On Windows, this relies on:

1. WinDivert — kernel driver for packet interception (Windows-only)
2. meter-core-rs — packet parsing and decryption logic (private repository)

On Linux, packet capture itself is straightforward via libpcap or AF_PACKET sockets (no special drivers needed, just CAP_NET_RAW capability). The real blocker is the packet parsing and decryption logic inside meter-core-rs.

Request

I understand the encryption/decryption code is kept private for security reasons. However, I'd like to ask if any of the following would be possible:

1. Abstract the capture layer: If meter-core-rs could expose a trait/interface for the packet capture backend (separating capture from parsing), a Linux implementation using libpcap could be plugged in without exposing any decryption logic.

2. Provide a pre-compiled Linux binary/library: A .so shared library of meter-core-rs compiled for Linux x86_64 would allow the live meter to work without exposing source code.

3. Any guidance on the architecture: Even a high-level overview of how meter-core-rs interfaces with the rest of the app (the start_capture function signature, packet flow, etc.) would help understand what's needed.

Lost Ark runs on Linux via Steam Proton, and there's a growing community of Linux players who would benefit from having the DPS meter available natively.

Environment

• OS: CachyOS (Arch-based), kernel 6.18.13-2-cachyos-lts
• Rust: 1.93.1
• Node: 25.6.1
• Tauri: 2.9.5
• Display: Wayland (with XWayland fallback for WebKitGTK)

Thank you for the amazing work on LOA Logs! Happy to contribute the Linux port changes back via PR if there's interest.
