@ -411,11 +411,11 @@ By using a trait bound with an `impl` block that uses generic type parameters,
we can implement methods conditionally for types that implement the specified
traits. For example, the type `Pair<T>` in Listing 10-16 always implements the
`new` function to return a new instance of `Pair<T>` (recall from the
[”Defining Methods”][methods] section of Chapter 5 that `Self` is a type alias
for the type of the `impl` block, which in this case is `Pair<T>`). But in the
next `impl` block, `Pair<T>` only implements the `cmp_display` method if its
inner type `T` implements the `PartialOrd` trait that enables comparison *and*
the `Display` trait that enables printing.
