Defines PartialEq, Eq, and Hash to compare the given struct/union/enum by address to other instances. This allows you to easily work with these items in hashing contexts (HashSets, HashMaps, etc.) whereby equality is defined by instance irrespective of content.

Example usage

use compare_by_address_derive::CompareByAddress;

#[derive(CompareByAddress)]
struct SomeStruct {
  // ...
}
