c2rust

Converts C function definitions to Rust. Use this tool to help in the creation of foreign function interfaces.

Pros

• super simple

$ ./c2rust.py "int foo(const char *s, unsigned long len)"
pub fn foo(s: *const c_char, len: c_ulong) -> c_int;

Cons

Does not handle:

• C preprocessor instructions
  • #include
  • macros
• variadic functions
• ...

For a more sophisticated tool take a look at rust-bindgen.

Usage

$ ./c2rust.py --help
