Crate tokio_dns 

This crate offers tools for asynchronous name resolution, and extensions to the tokio_core crate.

First, Endpoint and ToEndpoint behave very much like SocketAddr and ToSocketAddrs from the standard library. The main difference is that the ToEndpoint trait does not perform any name resolution. If simply detect whether the given endpoint is a socket address or a host name. Then, it is up to a resolver to perform name resolution.

The Resolver trait describes an abstract, asynchronous resolver. This crate provides one (for now) implementation of a resolver, the CpuPoolResolver. It uses a thread pool and the ToSocketAddrs trait to perform name resolution.

The crate level functions tcp_connect, tcp_listen and udp_bind support name resolution via a lazy static CpuPoolResolver using 5 threads. Their *_with counterpart take a resolver as an argument.
