parse enumeration

[vinniefalco]

There should be an enumeration or something, to indicate how a URL string should be parsed, e.g.

enum class kind {
  url,
  absolute_uri,
  relative_ref,
  origin_form,
  absolute_form,
  authority_form
};

See https://tools.ietf.org/html/rfc7230#section-5.3

This is done, and without the enum. Instead, we just have a family of functions like parse_uri, parse_relative_ref, and so on. And you can build your own parsing functions since the library gives you the primitives to put together.
