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.

impl PartialEq<SearchStep> for SearchStep

source§

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

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

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