Companies modernizing legacy C systems want to use Rust but often need to produce C code for compatibility. Manual conversion is time-consuming and error-prone.
Create a transpiler that converts idiomatic Rust to C with memory safety annotations and automated tests. Focus on producing human-readable C that maintains Rust's safety where possible.
Sell to engineering teams through GitHub sponsors or a commercial license. Start with a basic subset of Rust before expanding.
The complex semantics of both languages makes full translation challenging, so managing expectations would be key.
