Struct DigestFilter 

pub struct DigestFilter { /* private fields */ }

Digest filter implementation backed by a HashSet.

This implementation offers much better memory efficiency when compared to the NaiveFilter due to the fact that raw values are hashed to usize values before being stored in the set.

It’s also a little faster due to some improved efficiency when comparing values in the set itself, but it’s not of any real consequence and is barely noticeable.
