Cloning hash state #89

Closed rausm closed 5 years ago

rausm commented 7 years ago

Hi,

I needed to copy the hashing state (avoiding recomputation for common prefixes). Following worked well, and I'd like it to be included (IMO commonly supported functionality).

copy(hsh:: Hasher) = Hasher(hsh.hash_type, copy(hsh.state))

Thanks.

edit: ping @staticfloat
