This is a type for efficiently and easily constructing the part of a URL after the domain: `nightly/core/str/struct.Bytes.html`. It allows simplifying some code and avoiding some allocations in the `href_*` functions. It will also allow making `Cache.paths` et al. use `Symbol` without having to allocate `String`s in the `href_*` functions. `String`s would be necessary otherwise because `Symbol::as_str()` returns `SymbolStr`, whose `Deref<Target = str>` impl requires the `str` to not outlive it. This is the primary motivation for the addition of `UrlPartsBuilder`.
