Struct PatternMatcher 

pub struct PatternMatcher { /* private fields */ }

High-performance pattern matcher using Aho-Corasick for literal patterns and compiled regex for regex patterns

Implementations

impl PatternMatcher

pub fn new(patterns: Vec<Pattern>) -> Result<Self>

Create a new pattern matcher from a list of patterns

pub fn empty() -> Self

Create an empty pattern matcher

pub fn pattern_count(&self) -> usize

Get the total number of patterns

pub fn is_empty(&self) -> bool

Check if the matcher has any patterns

pub fn find_matches(&self, input: &str) -> Vec<Match>

Find all matches in the input text.

Input is normalized (NFKD + ZWC stripping) before matching to prevent homoglyph and zero-width character bypass attacks.

pub fn is_match(&self, input: &str) -> bool

Check if the input contains any matches.

Input is normalized (NFKD + ZWC stripping) before matching.

pub fn find_first(&self, input: &str) -> Option<Match>

Find the first match in the input.

Input is normalized (NFKD + ZWC stripping) before matching.

pub fn highest_severity(&self, input: &str) -> Option<Severity>

Get the highest severity among all matches

Trait Implementations

impl Debug for PatternMatcher

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

Formats the value using the given formatter.

impl Default for PatternMatcher

fn default() -> Self

Returns the “default value” for a type.
