RustMap introduces a novel hybrid approach combining program analysis with LLMs to transform C code into safer, idiomatic Rust while preserving functionality.

• Overcomes limitations of template-based translators by analyzing program dependencies and semantics
• Produces more memory-safe code that aligns with Rust's ownership model
• Generates human-readable, maintainable Rust code that reduces the need for unsafe blocks
• Leverages LLMs to handle complex translation challenges where rules-based approaches fail

This research addresses critical engineering needs by enabling organizations to migrate legacy C codebases to Rust without sacrificing safety or performance—making it easier to modernize critical infrastructure while reducing security vulnerabilities.
