bitser LuaJIT serialization library.
$ luarocks install --server=https://luarocks.org/dev bitser
Serializes and deserializes Lua values with LuaJIT.
Please note that bitser requires LuaJIT for its ffi library and JIT compilation. Without JIT, it may or may not run, but it will be much slower than usual. This primarily affects Android and iOS, because JIT is disabled on those platforms.
