externaldns

This lib implenments External-DNS webhook interface. External-DNS uses this interface to communicate with non-built-in DNS service provider.

The main trait is Provider, which defines the four functions of the webhook. Pass the implementor to Webhook::new, then Webhook::start to get the whole thing running.
