The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
