A Rust based DNS client and server, built to be safe and secure from the ground up. Using the ClientFuture is safe. ClientFuture is a brand new rewrite of the old Client. It has all the same features as the old Client, but is written with the wonderful futures-rs library. Please send feedback! It currently does not cache responses, if this is a feature you'd like earlier rather than later, post a request. The validation of DNSSec is complete including NSEC. As of now NSEC3 is broken, and I may never plan to support it. I have some alternative ideas for private data in the zone. The old Client has been deprecated, so please use the ClientFuture. If this is an inconvenience, I may add a convenience wrapper around ClientFuture that would match the old Client; if this is something you would like to see, please file an issue.
