I’m a fairly experienced Rustacean with a strong background in
unsafe and FFI, and would like to help port existing C codebase to Rust. The Contributing to the Tectonic Project page has a Working on the Source Code section saying the eventual goal is to port everything to Rust, but doesn’t go into much detail on the how.
So how can I get started? Is there an existing process for porting across? Maybe something like how remacs ports primitive functions across?
