Zones in link-local IPv6 addresses seems to be not supported.

[vi]

extern crate http;

fn main() {
    use http::uri::Uri;
    use std::str::FromStr;
    Uri::from_str("http://[fe80::1%25eth0]:8080/").unwrap();
}

InvalidUri(InvalidAuthority).

It parses if I omit the zone index (%25eth0), but such URI is expected to be unconnectable by itself.

Should http crate support RFC6874 and allow link-local IPv6 in URLs?

For what it's worth, SocketAddr::parse does not handle this address either: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=ac423a008035b1e29562123d416fa551

Yet there is scope_id in SockAddrV6, an u32 field.

Filling it in from parse requires querying network interfaces information in a platform-specific way although.

P.S. For SocketAddr::parse it shouldn't be URL-encoded: [fe80::1%eth0]:80.

If we prepared a patch to introduce this feature would it be accepted?

If it is valid in the http spec and doesn’t break anything (both which sound correct) then yes!
