Enum memchr::memmem::searcher::SearcherRevKind

enum SearcherRevKind {
    Empty,

    TwoWay {

}

The kind of the reverse searcher.

For the reverse case, we don’t do any SIMD acceleration or prefilters. There is no specific technical reason why we don’t, but rather don’t do it because it’s not clear it’s worth the extra code to do so. If you have a use case for it, please file an issue.

We also don’t do the union trick as we do with the forward case and prefilters. Basically for the same reason we don’t have prefilters or vector algorithms for reverse searching: it’s not clear it’s worth doing. Please file an issue if you have a compelling use case for fast reverse substring search.
