Struct trust_dns_proto::xfer::DnsExchangeConnect [−][src]
A wrapper for a future DnsExchange connection.
DnsExchangeConnect is clonable, making it possible to share this if the connection will be shared across threads.
The future will return a tuple of the DnsExchange (for sending messages) and a background for running the background tasks. The background is optional as only one thread should run the background. If returned, it must be spawned before any dns requests will function.
