Overview

Package client contains the implementations required for plugins to act as a client. Developers typically query via the Runner interface, so they don't need to be aware of this layer.

The client is the actual entity that satisfies the interface. It sends a request to the host via RPC, decodes the response, and provides APIs for plugins.

Complex structures such as hcl.Expression and hcl.Body are sent/received as byte slices and range. Plugins and host parse the byte slice to get the original object.
