Better docs for edge-cases on getters about rust-url HOT 4 CLOSED

Sigh. I wish rustdoc had cross-references, so that every mention "relative scheme" could be linked to its definition without hard-coding the link in the source.

Regarding when it’s None, http://servo.github.io/rust-url/url/index.html#url-parsing-and-data-structures is relevant. Looking at how Url, SchemeData, and RelativeSchemeData relate to each other may help. I blame rustdoc for being "API-first" and not allowing me to introduce things in the order that makes most sense for readers.

A trailing slash corresponds to an empty string in the last path components. The parser always gives path always at least one component. http://exmaple.net and http://exmaple.net/ (they are equivalent) have one path component, the empty string.

@SimonSapin Thanks for the info, much appreciated. I guess that since this is documented somewhere this isn't really an issue so much as my lack of skill with the search field :).

@reem Is this still an issue, can we close this?

Can be closed, since the docs are given, I just couldn't find them.
