Enum url::Host

source ·
pub enum Host<S = String> {
    Domain(S),
    Ipv4(Ipv4Addr),
    Ipv6(Ipv6Addr),
}
Expand description

The host name of an URL.

Variants§

§

Domain(S)

A DNS domain name, as ‘.’ dot-separated labels. Non-ASCII labels are encoded in punycode per IDNA if this is the host of a special URL, or percent encoded for non-special URLs. Hosts for non-special URLs are also called opaque hosts.

§

Ipv4(Ipv4Addr)

An IPv4 address. Url::host_str returns the serialization of this address, as four decimal integers separated by . dots.

§

Ipv6(Ipv6Addr)

An IPv6 address. Url::host_str returns the serialization of that address between [ and ] brackets, in the format per RFC 5952 A Recommendation for IPv6 Address Text Representation: lowercase hexadecimal with maximal :: compression.
