Crate luars_derive 

Procedural macros for luars userdata system.

Macros provided

• #[derive(LuaUserData)] — auto-generate UserDataTrait for structs (field access via get_field/set_field, metamethods via #[lua_impl(...)])

• #[lua_methods] — attribute macro on impl blocks, generates static C wrapper functions for each pub fn, accessible from Lua via obj:method(...) calls

Architecture

• derive_userdata.rs — #[derive(LuaUserData)] implementation
• lua_methods.rs — #[lua_methods] implementation
• type_utils.rs — shared type conversion helpers (Rust ↔ UdValue ↔ LuaValue)

Attribute Macros

lua_methods

Attribute macro on impl blocks — exposes public methods to Lua.
