in_addr

This crate exposes a common interface to in_addr between Unix and Windows. Get rid of these #[cfg]s!

Features

• no-std: Compile this crate with no_std. Conversions to and from std::net::Ipv4Addr will not be available.

Documentation

• cfg(windows): https://docs.rs/in_addr/*/x86_64-pc-windows-msvc/in_addr/
• cfg(unix): https://docs.rs/in_addr/*/x86_64-unknown-linux-gnu/in_addr/

lib.rs:

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());
}
