There was a problem hiding this comment.
I don't think this is correct, since it is hashing the underlying storage as well as the semantic value. I think this will mean let x = BitvSet::new(); x.insert(1000); x.remove(1000); hashes differently to just BitvSet::new() even though they are semantically identical (see the implementation of PartialEq).

@huonw updated. The impl for BitvSet is slower than it could be because I'm not sure there's any guarantee that the BigBitv is as small as possible at all times. |
