@porglezomp@shanecelis although, it would appear that this library is not without some of the general problems mentioned in article https://github.com/mlua-rs/mlua/issues/318 (in this case a relatively normal task being 14 times slower to do in Rust than Lua because Rust demands it so)
I'm sure it's probably fine for basic use though and you can likely adapt your Lua code around the library's limitations because Lua is nice like that.
