Also known as rdms_proc_macros. This crate contains proc macros used by either or both Readymade and Taidan.
The code was originally extracted from Taidan itself. Specifically, the generation of language list during compile-time was handled in this crate and used by Taidan, and later Readymade borrowed the same macro.
We choose to not publish this crate and instead make it used as a submodule in RDMS to speed up development.
