Function set_userdata_remapper 

pub fn set_userdata_remapper(
    L: *mut lua_State,
    context: *mut c_void,
    cb: UserdataRemapperCallback,
)

Sets the userdata remapper callback and context on the code generation context.

Mirrors setUserdataRemapper (CodeGen/src/CodeGenContext.cpp):

void setUserdataRemapper(lua_State* L, void* context, UserdataRemapperCallback cb) {
    if (BaseCodeGenContext* codegenCtx = getCodeGenContext(L)) {
        codegenCtx->userdataRemappingContext = context;
        codegenCtx->userdataRemapper = cb;
        L->global->ecb.gettypemapping = cb ? userdataRemapperWrap : nullptr;
    }
}

Safety

• L must be a valid, non-null pointer to a lua_State.
• The global state (L->global) must be valid and initialized.
• The code generation context must be valid and properly initialized.
• The callback cb must be a valid function pointer.
