/// A component that represents Uri-Path options.
///
/// This is typically either of:
/// * [`&[str]`]: the raw URI path components.
/// * [`str`]: a URI refernce in path-absolute form (starting with a slash). It will produce its
///   slash-separated segments, and end before the query identifier (question mark, `?`) or the
///   fragment identifier (hash sign, `#`) if any is present to stay within the regular URI
///   conventions.
