Been rocking Rust for my projects lately and honestly, it is a breath of fresh air compared to the usual C++ boilerplate. While everyone is still copypasting WinAPI wrappers, moving to syscall-level logic in Rust changes the game for injectors and loaders.
Why pivot from C++?
We all know C++ with WinAPI is the industry standard, but when you are fighting modern anti-cheats like EAC or BattlEye, you need more than just standard calls. Rust gives you that granular memory control without the overhead of a heavy runtime, making it ideal for stealthy memory manipulation.
Technical Advantages:
Bypassing Detection Vectors
Advanced kernel drivers are nuking standard userland injection methods. By using trampolines to mimic kernel-mode behavior while staying in userland, you significantly reduce the attack surface. It makes the injection path a nightmare to trace for heuristic scanners. It is not a silver bullet, but it raises the bar significantly.
Anyone else moving their codebase over to Rust? I am curious if you guys have found any significant overhead issues or if you are sticking to the C++ old guard for legacy reasons.
who is currently porting their loaders to rust?

Technical Advantages:
- Manual Syscall Resolution — Instead of loading ntdll.dll and leaving a massive trace for the anti-cheat to find, you can resolve syscall numbers at runtime. This allows you to inject into a target process while bypassing common userland hooks.
- Inline Assembly — Rust's asm macro is a godsend. No need for external .asm files or messy build scripts; you bake the logic directly into the binary, keeping it portable and harder to signature.
- Memory Safety in Unsafe Blocks — Even when you are doing raw pointer arithmetic, the compiler still catches the stupid logic errors that usually lead to a random crash or a BSOD in C++ builds.
- UI with egui — If you need a menu or a standalone loader interface, egui is surprisingly lightweight and fast for game overlays or external tools without the bloat of ImGui-node-js wrappers.

- Language: Rust (Stable/Nightly for specific asm features)
- UI: egui / macroquad
- Low-level: Manual syscalls, custom PE loaders, ntdll mapping
- Targeting: Userland to Kernel trampoline simulation
