Struct aho_corasick::packed::Config

pub struct Config { /* private fields */ }

The configuration for a packed multiple pattern searcher.

The configuration is currently limited only to being able to select the match semantics (leftmost-first or leftmost-longest) of a searcher. In the future, more knobs may be made available.

A configuration produces a packed::Builder, which in turn can be used to construct a packed::Searcher for searching.

Example

This example shows how to use leftmost-longest semantics instead of the default (leftmost-first).

use aho_corasick::{packed::{Config, MatchKind}, PatternID};

let searcher = Config::new()
    .match_kind(MatchKind::LeftmostLongest)
    .builder()
    .add("foo")
    .add("foobar")
    .build()?;
let matches: Vec<PatternID> = searcher
    .find_iter("foobar")
    .map(|mat| mat.pattern())
    .collect();
assert_eq!(vec![PatternID::must(1)], matches);

Implementations

impl Config

pub fn new() -> Config

Create a new default configuration. A default configuration uses leftmost-first match semantics.

pub fn builder(&self) -> Builder

Create a packed builder from this configuration. The builder can be used to accumulate patterns and create a Searcher from them.

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

Set the match semantics for this configuration.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.
