For any other use case, I would have recommended Rust, but for making a hobby game engine, I would advise not using either rust or Odin and instead use C and C++. The graphics drivers have a primary C Abi and you would spend a really long time debugging C to Odin/Rust translation layer bugs than actually working on he engine.
I would suggest write a C rendering library, wrap it in safe Rust and move on from there.
LFS is the only true distro
