pub unsafe extern "C" fn pushlightuserdata(
state: lua_State,
ptr: *const c_void,
)Expand description
Pushes a light userdata onto the stack.
Userdata represent C values in Lua A light userdata represents a pointer. It is a value (like a number): you do not create it, it has no individual metatable, and it is not collected (as it was never created). A light userdata is equal to “any” light userdata with the same C address.
