//! A safe wrapper for the [`c-ares`](http://c-ares.haxx.se) library.
//!
//! Usage is as follows:
//!
//! -  Create a `Channel`.
//!
//! -  Make queries on the `Channel`.  Queries all take callbacks, which will
//!    be called when the query completes.
//!
//! -  Have `c-ares` tell you what file descriptors to listen on for read and /
//!    or write events.  You can do this either by providing a callback, which
//!    is called whenever the set of interesting file descriptors changes, or
//!    by querying the `Channel` directly with `get_sock()`.
//!
//! -  Do as `c-ares` asks!  That it, listen for the events that it requests,
//!    on the file descriptors that it cares about.
//!
//! -  When a file descriptor becomes readable or writable, call `process_fd()`
//!    on the `Channel` to tell `c-ares` what has happened.
//!
//! -  If you have queries pending and don't see events happening, you still
//!    need to call `process_fd()` at some point anyway - to give `c-ares` an
//!    opportunity to process any requests that have timed out.
//!
//! Complete examples showing how to use the library can be found
//! [here](https://github.com/dimbleby/rust-c-ares/tree/master/examples).
