pub unsafe extern "C" fn settable(state: lua_State, index: i32)Expand description
Does the equivalent to t[k] = v, where t is the value at the given valid index, v is the value at the top of the stack, and k is the value just below the top.
This function pops both the key and the value from the stack. As in Lua, this function may trigger a metamethod for the “newindex” event (see §2.8).
