# Enum core::str::pattern::SearchStep
[−][src]

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

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

API not fully fleshed out and ready to be stabilized

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

## Variants

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

API not fully fleshed out and ready to be stabilized

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)

API not fully fleshed out and ready to be stabilized

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)

API not fully fleshed out and ready to be stabilized

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