# Enum alloc::str::pattern::SearchStep

source ·

    pub enum SearchStep {
        Match(usize, usize),
        Reject(usize, usize),
        Done,
    }

🔬This is a nightly-only experimental API. (`pattern` #27721)
Expand description

Result of calling `Searcher::next()` or `ReverseSearcher::next_back()`.

## Variants§

§

### Match(usize, usize)

🔬This is a nightly-only experimental API. (`pattern` #27721)

Expresses that a match of the pattern has been found at `haystack[a..b]`.

§

### Reject(usize, usize)

🔬This is a nightly-only experimental API. (`pattern` #27721)

Expresses that `haystack[a..b]` has been rejected as a possible match of the pattern.

Note that there might be more than one `Reject` between two `Match`es, there is no requirement for them to be combined into one.

§

### Done

🔬This is a nightly-only experimental API. (`pattern` #27721)

Expresses that every byte of the haystack has been visited, ending the iteration.
