Fil-C Improves Rust FFI Memory Safety for Legacy C Code

TL;DR. Fil-C offers a new approach for Rust to interact with C/C++ libraries, enabling memory safety through runtime checks and garbage collection. - Fil-C recompiles C/C++ with capabilities and runtime checks, converting memory safety violations into panics instead of exploits. - This allows legacy C code to integrate with Rust's compile-time safety, providing a secure bridge for interoperability. - The system introduces a performance penalty for C code, incentivizing migration of critical paths to Rust for static safety. - Projects like filnix and Zig's proposed 'fil' ABI are advancing implementations for this type of memory-safe C integration.

• Fil-C adds runtime memory safety checks to C/C++ code.
• Rust FFI integration allows safe interaction with recompiled C/C++.
• Performance penalty for C code encourages Rust migration for hot paths.
• Filnix project provides toolchain for Fil-C cross-compilation.
