I want to get the offset of fields inside structs, but I don't want to instantiate the struct. I need to embed the offsets inside machine code, and I can't get the offsets without calling `new` on the struct. This commit adds an `offset` method so you can get the offset of a member without instantiating anything. You can do: ```ruby C.rb_control_frame_t.offsetof(:sp) #=> 8 ``` I don't think this implementation is perfect, you can only get immediate fields. But it is better than nothing! |
