pub fn build_query_string(query: &Query) -> StringExpand description
Build the wire-format query string to send over the TCP connection.
Per RFC 1288:
- Verbose queries prepend
/W(with trailing space). - Forwarding appends
@host1@host2...for all hosts except the last (the last host is the connection target, not part of the query string). - The query is terminated with
\r\n.
