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.
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.
