Function memchr::memmem::searcher::prefilter_kind_fallback

unsafe fn prefilter_kind_fallback(
    strat: &Prefilter,
    haystack: &[u8],
) -> Option<usize>

Reads from the fallback field of PrefilterKind to execute the fallback prefilter. Works on all platforms.

Safety

Callers must ensure that the strat.kind.fallback union field is set.
