Host

Enum Host 

Source
pub enum Host<'a> {
    Name(&'a [u8]),
    V4(Ipv4Addr),
    V6(Ipv6Addr),
    Future(&'a [u8]),
}
Expand description

A host: a registered name, an IP address, or a future IP literal.

§Examples

use core::net::Ipv4Addr;
use parse_net::{parse_host_port, Host};

assert_eq!(parse_host_port(b"192.0.2.1")?.host, Host::V4(Ipv4Addr::new(192, 0, 2, 1)));
assert_eq!(parse_host_port(b"example.com")?.host, Host::Name(b"example.com"));
assert_eq!(parse_host_port(b"[v1.fe]")?.host, Host::Future(b"v1.fe"));

Variants§

§

Name(&'a [u8])

A registered name (reg-name), as sent: case and a trailing dot are kept, %XX triples are not decoded. Empty when the field was empty.

§

V4(Ipv4Addr)

A dotted-decimal IPv4 address.

§

V6(Ipv6Addr)

A bracketed IPv6 address.

§

Future(&'a [u8])

A bracketed IPvFuture literal (vX.yyy), without the brackets.

Implementations§

Source§

impl Host<'_>

Source

pub fn eq_ignore_ascii_case(&self, other: &Host<'_>) -> bool

Whether two hosts are the same: names compared ASCII case-insensitively, IP literals by value.

§Examples
use parse_net::host::parse_host;

assert!(parse_host(b"Example.com")?.eq_ignore_ascii_case(&parse_host(b"example.COM")?));
assert!(parse_host(b"[::1]")?.eq_ignore_ascii_case(&parse_host(b"[0:0::1]")?));
Source

pub fn is_empty(&self) -> bool

Whether this is the empty name of an empty Host field.

§Examples
use parse_net::parse_host_port;

assert!(parse_host_port(b"")?.host.is_empty());
assert!(!parse_host_port(b"example.com")?.host.is_empty());
Source

pub fn write_to(&self, out: &mut impl Sink) -> Result<(), WriteError>

Writes the host: names as given, IPv6 bracketed in its RFC 5952 form.

§Errors

WriteError::Full; nothing is written when the sink reports its room.

§Examples
use parse_net::{host::parse_host, SliceSink};

let mut buf = [0u8; 64];
let mut out = SliceSink::new(&mut buf);
parse_host(b"[2001:DB8:0:0:0:0:0:1]")?.write_to(&mut out).expect("room");
assert_eq!(out.written(), b"[2001:db8::1]");
