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. It makes use of the
proc-macro hack and is compatible
with stable rust. Inspired by the maplit
crate.
Example:
#[macro_use]
extern crate net_literals;
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()
);
}
