Enum 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.

Trait Implementations

impl Clone for SearchStep

fn clone(&self) -> SearchStep

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SearchStep

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for SearchStep

fn eq(&self, other: &SearchStep) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
