You're not treating this fields as arrays of 32-bit integers (and semantically, I don't think they
are defined that way anyway), so why define them as such?  If you change them to [u8; then you might
not need .as_bytes_mut() in the next patch.  This also avoids any endian weirdness that can occur. 
Plus, you'll be able to do this:

	hash384: [u8; FSP_HASH_SIZE]
