-// TODO we could avoid many of these getter string allocatoration in two differents
-// way:
-//
-// 1. We can eventually get the slice of scheme *with* the following char in
-// the underlying string. But I don't know if it's possible and how to do that.
-// I mean, if the rawuri contains `https://foo.bar`, uri.scheme is a slice
-// containing only `https`. I want `https:` so, in theory, I don't need to
-// allocatorate data, I should be able to retrieve the scheme + the following `:`
-// from rawuri.
-//
-// 2. The other way would be to copy the `std.Uri` code to have a dedicated
