Enum std::str::pattern::SearchStep

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].

Tuple Fields of Match

0: usize

API not fully fleshed out and ready to be stabilized

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 Matches, there is no requirement for them to be combined into one.

Tuple Fields of Reject

0: usize

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

1: usize

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

API not fully fleshed out and ready to be stabilized

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.
