Tyson Nottingham d061fee177 Stable hashing: add comments and tests concerning platform-independence ... SipHasher128 implements short_write in an endian-independent way, yet its write_xxx Hasher trait methods undo this endian-independence by byte swapping the integer inputs on big-endian hardware. StableHasher then adds endian-independence back by also byte-swapping on big-endian hardware prior to invoking SipHasher128. This double swap may have the appearance of being a no-op, but is in fact by design. In particular, we really do want SipHasher128 to be platform-dependent, in order to be consistent with the libstd SipHasher. Try to clarify this intent. Also, add and update a couple of unit tests.		2020-09-30 00:57:35 -07:00
