URI: how to distinguish from invalid port vs no port number

[niklasad1]

Hey,

I read that default port was rejected in #11.

However, the current API has pub fn port(&self) -> Option<Port<&str>> but it's not possible to
distinguish when invalid port number vs when no port number.
.
Example:

let uri: Uri = "/hello/world".parse().unwrap();
assert!(uri.port().is_none());

let uri: Uri = "/hello/world:-9933".parse().unwrap();
assert!(uri.port().is_none());

Opinions about having pub fn port(&self) -> Result<Option<Port<&str>, Error> or something similar?

What is the rationale for not returning an error on invalid port numbers?

It probably should return an error when the Uri/Authority itself is parsed, not when calling the accessor.

That is what I meant
