ParseHashV validates the length and encoding of the string and throws an informative RPC error on failure, which is as good or better than these alternative calls. Note I switched ParseHashV to check string length first, because IsHex tests that the length is even, and an error like: "must be of length 64 (not 63, for X)" is much more informative than "must be hexadecimal string (not X)"
