net-literals: Rust macros for writing IP/socket address literals.

This crate allows you to write IP and socket addresses as strings which are parsed (and checked for validity) at compile time. Inspired by the maplit crate.

Example:

use net_literals::{ip, ipv4, ipv6, addr, addrv4, addrv6};
use std::net::{IpAddr, Ipv4Addr, Ipv6Addr};
use std::net::{SocketAddr, SocketAddrV4, SocketAddrV6};
use std::str::FromStr;

fn main() {
    assert_eq!(
        ip!("1.2.3.4"),
        IpAddr::from_str("1.2.3.4").unwrap()
    );

    assert_eq!(
        ipv4!("1.2.3.4"),
        Ipv4Addr::from_str("1.2.3.4").unwrap()
    );

    assert_eq!(
        ipv6!("0011:2233:4455:6677:8899:aabb:ccdd:eeff"),
        Ipv6Addr::from_str("0011:2233:4455:6677:8899:aabb:ccdd:eeff").unwrap()
    );

    assert_eq!(
        addr!("2.3.4.5:666"),
        SocketAddr::from_str("2.3.4.5:666").unwrap()
    );

    assert_eq!(
        addrv4!("2.3.4.5:666"),
        SocketAddrV4::from_str("2.3.4.5:666").unwrap()
    );

    assert_eq!(
        addrv6!("[::2345]:666"),
        SocketAddrV6::from_str("[::2345]:666").unwrap()
    );
}
