Is blake2 require or is using blake3 possible?

[Redhawk18]

I was reading the specs page and wondering since blake3 is out if it would be possible to use that instead? I'm new to all of this but I don't think these two libraries give the same hash, but I'm not sure.

I know its rust, but they have doc pages with function signatures. But would this work?
