It is worth noting that this new form of default implementation is different from the blanket implementation that we are used to. In particular, if we go back to our previous example, we would find that we can no longer use the default implementation of T implementing Display to use the Hash trait inside our generic function. This makes sense, because the correct Hash implementation can now only be chosen when the concrete type is known.
