Method is_match_at

regex/src/re_unicode.rs:641–643

Returns the same as is_match, but starts the search at the given offset. The significance of the starting point is that it takes the surrounding context into consideration. For example, the `\A` anchor can only match when `start == 0`.

(&self, text: &str, start: usize)

    /// context into consideration. For example, the `\A` anchor can only
    /// match when `start == 0`.
    pub fn is_match_at(&self, text: &str, start: usize) -> bool {
        self.shortest_match_at(text, start).is_some()
    }

    /// Returns the same as find, but starts the search at the given
    /// offset.
