Crate intersection

Expand description

A crate to find the intersection between a collection of sets. Convenient when your collection of sets consists of more than 2 sets.

There are two options:

With HashSet, use hash_set::intersection.
With BTreeSet, use btree_set::intersection.

Why use this over HashSet::intersection or BTreeSet::intersection?

The standard library intersection methods require a bit of ceremony when you want to intersect 3 or more sets with each other. These intersection(other: &Set) methods produce a lazy iterator, which you then have to wrap into a HashSet::from_iter again. An alternative way is to use the BitAnd implementation of either set. In both cases it requires a bit of boilerplate which this library does for you =).
