Function span

regex/regex-syntax/src/ast/parse.rs:2343–2347

Create a new span from the given offset range. This assumes a single line and sets the columns based on the offsets. i.e., This only works out of the box for ASCII, which is fine for most tests.

(range: Range<usize>)

    /// line and sets the columns based on the offsets. i.e., This only works
    /// out of the box for ASCII, which is fine for most tests.
    fn span(range: Range<usize>) -> Span {
        let start = Position::new(range.start, 1, range.start + 1);
        let end = Position::new(range.end, 1, range.end + 1);
        Span::new(start, end)
    }

    /// Create a new span for the corresponding byte range in the given string.
