An utility crate to retrieve the DNS resolvers of the underlying host OS.

On UNIX-like platforms, it merely read the /etc/resolv.conf file.

On Windows, it uses the windows crate and calls the dedicated APIs to get the list of DNS resolvers for all interfaces (GetAdaptersAddresses). In addition on this platform, the ability to provide a interface index or interface name to all get the resolvers on those.

Usage:

use resolver::ResolverList;
let addresses = ResolverList::new().expect("failed to load DNS addresses");

println!("{} addresses found", addresses.len());
