Indeed, OpenResty comes with Lua and LuaJIT built-in. Earlier version where we've implemented all in Lua, had no need for that. However, as we went fro Lua to Rust (and speed up by using only 15% CPU comparing to the Lua), we added that Lua interface support to the rust, and it worked like a charm.
