FuzzyRegexBuilder

Builder for customizing regex construction.

Basic Usage

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("(?:hello)")
        .build()
        .unwrap();
    
    println!("Created");
}

Builder Options

Similarity Threshold

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("(?:hello){e<=2}")
        .similarity(0.8)  // Minimum similarity 0.0-1.0
        .build()
        .unwrap();
    
    println!("Created");
}

Case Insensitivity

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("(?:hello)")
        .case_insensitive(true)
        .build()
        .unwrap();

    assert!(re.is_match("HELLO"));
    assert!(re.is_match("Hello"));
}

Multi-line Mode

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("^hello$")
        .multi_line(true)  // ^ and $ match line boundaries
        .build()
        .unwrap();
    
    println!("Created");
}

Dot-all Mode

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("a.b")
        .dot_all(true)  // . matches newlines
        .build()
        .unwrap();
    
    println!("Created");
}

Partial Matching

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("(?:hello){e<=1}")
        .partial(true)  // Matches at end of text are partial
        .build()
        .unwrap();

    let m = re.find("hello").unwrap();
    assert!(m.partial()); // Match reaches end of text
}

Timeout

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;
    use std::time::Duration;

    let re = FuzzyRegexBuilder::new("(?:hello){e<=5}")
        .timeout(Duration::from_millis(100))
        .build()
        .unwrap();
    
    println!("Created");
}

Chaining Options

fn main() {
    use fuzzy_regex::FuzzyRegexBuilder;

    let re = FuzzyRegexBuilder::new("(?:hello){e<=1}")
        .case_insensitive(true)
        .similarity(0.7)
        .partial(true)
        .multi_line(true)
        .build()
        .unwrap();
    
    println!("Created");
