Crate multimatch 

multimatch

Multi-pattern matching engine for security scanning.

Every security tool needs to search text for many patterns simultaneously: secret scanners match 1000+ credential regexes, vulnerability scanners match response signatures, taint analyzers match sink patterns.

This crate provides a unified interface for the currently implemented backend:

• Aho-Corasick + regex — always available, zero external dependencies

Usage

use multimatch::{PatternSet, MatchResult};

let patterns = PatternSet::builder()
    .add_literal("password", 0)
    .add_literal("secret", 1)
    .add_regex(r"[A-Za-z0-9]{32,}", 2)
    .build()
    .unwrap();

let matches = patterns.scan(b"my password is abc123secretXYZ");
assert!(matches.iter().any(|m| m.pattern_id == 0)); // "password"
assert!(matches.iter().any(|m| m.pattern_id == 1)); // "secret"
