Is it possible to update a hash incrementally?

[Crypto-Spartan]

Hi! Thank you for you work to port XXHash to Rust!

I would like to use this crate to hash large files that could be multiple gigabytes in size. Since it isn't practical to read the entire file into memory, my plan was to use a ReadBuf to read the file in chunks.

The Blake3 hashing algorithm allows for incremental updating of the hash with chunks of data. (See here)

I don't need the cryptographic security that Blake3 provides and I would rather use XXHash since it can process data much faster. Is something like this possible with twox-hash?

Yes, it implements the Hasher and (optionally) the Digest traits. Both of these allow passing in partial chunks of the whole data.

See examples in #70 and #42.

Assuming this answers your question
