Method is_match

regex/src/re_unicode.rs:197–199

Returns true if and only if the regex matches the string given. It is recommended to use this method if all you need to do is test a match, since the underlying matching engine may be able to do less work. # Example Test if some text contains at least one word with exactly 13 Unicode word characters: ```rust # extern crate regex; use regex::Regex; # fn main() { let text = "I categorically deny

(&self, text: &str)

    /// # }
    /// ```
    pub fn is_match(&self, text: &str) -> bool {
        self.is_match_at(text, 0)
    }

    /// Returns the start and end byte range of the leftmost-first match in
    /// `text`. If no match exists, then `None` is returned.
