A Rust wrapper for the c-ares library, for asynchronous DNS requests.

Most users should likely prefer c-ares-resolver, which offers a much simpler API.

• API documentation is here.
• There are some example programs here.

Setting the feature build-cmake will cause the c-ares library to be built using cmake. This is significantly faster than the default autotools build on unix platforms: so if it works for you, you should probably prefer it.
