Enum SearchStep

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

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

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

Variants

Match(usize, usize)

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

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)

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)

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.

impl Copy for SearchStep

impl Eq for SearchStep

impl StructuralPartialEq for SearchStep

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
