The existing Lua struct libraries [1][2][3] are very similar to the
Python one [4]. My library however takes a higher level approach where
you define named data types, and can combine them in complex manners.
While struct libraries are perfectly fine to describe C structures
containing only POD value, they are not capable of describing complex
file formats or network packets. This is where Lunary shines.
