Enum std::str::pattern::SearchStep

pub enum SearchStep {
    Match(usize, usize),
    Reject(usize, usize),
    Done,
}
🔬This is a nightly-only experimental API. (pattern #27721)

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 Matches, 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.

source 
impl PartialEq for SearchStep
source 
fn eq(&self, other: &SearchStep) -> bool
