How to document mlua modules?

[bobbens]

What is the best way to document mlua modules and exposed API?
For C code, I've been using doxygen style comments compatible with ldoc, using a script to generate some fake Lua with the comments and function names, then run ldoc on the generated file to generate the documentation. Is there a more Rust-ish way or better way to do that with mlua given that there is actual typing and such?
