//! This crate exposes a common interface to in_addr between Unix and Windows.
//!
//! There are two types in this crate.
//! * `in_addr`, a type alias to the platform specific version of this type. Use this in the
//!   signature of `extern` functions.
//! * `InAddr`, a newtype wrapper around `in_addr`. It implements conversions to and from `u32`,
//!   `std::net::Ipv4Addr`, and `in_addr`.
//!
//! # Example
//!
//! ```
//! extern {
//!   fn inet_ntoa(addr: *const in_addr::in_addr) -> *const std::os::raw::c_char;
//! }
//!
//! fn main() {
//!   let addr = in_addr::InAddr::new(std::net::Ipv4Addr::LOCALHOST);
//!   let addr_text = unsafe { std::ffi::CStr::from_ptr(inet_ntoa(&addr.into())) };
//!   println!("The address is {}.", addr_text.to_string_lossy());
//! }
//! ```
