Struct aho_corasick::packed::Config

source ·
pub struct Config { /* private fields */ }
Expand description

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§

source§

impl Config

source

pub fn new() -> Config

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

source

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.

source

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

Set the match semantics for this configuration.

source

pub fn heuristic_pattern_limits(&mut self, yes: bool) -> &mut Config

Request that heuristic limitations on the number of patterns be employed. This useful to disable for benchmarking where one wants to explore how Teddy performs on large number of patterns even if the heuristics would otherwise refuse construction.

This is enabled by default.
