Macros for writing literal IP addresses.
See <https://github.com/rust-lang/rfcs/issues/1926> for the background behind this crate.
## Rust nightly
This crate uses the recently implemented [procedural macros] feature, and so requires a nightly version of the compiler.
If you use [rustup][] (recommended), then you can install Rust nightly using [these instructions][nightly howto].
[procedural macros]: https://github.com/rust-lang/rust/issues/38356
[rustup]: https://rustup.rs/
[nightly howto]: https://github.com/rust-lang-nursery/rustup.rs#working-with-nightly-rust
## Example
```rust
#![feature(proc_macro)] // <- Don't forget this!!!
extern crate ip_macro;
use ip_macro::ip;
fn main() {
println!("There's no place like {}", ip!("127.0.0.1"));
}
```
