Struct ExternalMessagingAdapter 

pub struct ExternalMessagingAdapter { /* private fields */ }

Messaging adapter that delegates all operations to an external plugin process.

Each method call spawns a fresh process, sends one JSON request line to stdin, reads one JSON response line from stdout, then waits for exit.
