This inner class defines comparison operators available for T.
This inner class defines comparison operators available for T.
It can't extend AnyVal because it is not a top-level class or a member of a statically accessible object.

Returns an integer whose sign communicates how x compares to y.
Returns an integer whose sign communicates how x compares to y.
The result sign has the following meaning:
- negative if x < y - positive if x > y - zero otherwise (if x == y)

Given f, a function from T into S, creates an Ordering[T] whose compare function returns the result of this Ordering's compare function, if it is non-zero, or else a result equivalent to:
Ordering[S].compare(f(x), f(y))
This function is equivalent to passing the result of Ordering.by(f) to orElse.

Implementations overriding this method MUST override isReverseOf as well if they change the behavior at all (for example, caching does not require overriding it).
