Struct Builder

pub struct Builder { /* private fields */ }

A builder for configuring an Aho-Corasick noncontiguous NFA.

This builder has a subset of the options available to a AhoCorasickBuilder. Of the shared options, their behavior is identical.

Implementations

impl Builder

pub fn new() -> Builder

Create a new builder for configuring an Aho-Corasick noncontiguous NFA.

pub fn build<I, P>(&self, patterns: I) -> Result<NFA, BuildError>

where I: IntoIterator<Item = P>, P: AsRef<[u8]>,

Build an Aho-Corasick noncontiguous NFA from the given iterator of patterns.

A builder may be reused to create more NFAs.

pub fn match_kind(&mut self, kind: MatchKind) -> &mut Builder

Set the desired match semantics.

See AhoCorasickBuilder::match_kind for more documentation and examples.

pub fn ascii_case_insensitive(&mut self, yes: bool) -> &mut Builder

Enable ASCII-aware case insensitive matching.

See AhoCorasickBuilder::ascii_case_insensitive for more documentation and examples.

pub fn dense_depth(&mut self, depth: usize) -> &mut Builder

Set the limit on how many states use a dense representation for their transitions. Other states will generally use a sparse representation.

See AhoCorasickBuilder::dense_depth for more documentation and examples.

pub fn prefilter(&mut self, yes: bool) -> &mut Builder

Enable heuristic prefilter optimizations.

See AhoCorasickBuilder::prefilter for more documentation and examples.

Trait Implementations

impl Clone for Builder

fn clone(&self) -> Builder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
