Struct trust_dns_proto::xfer::DnsExchangeConnect

source · 
pub struct DnsExchangeConnect<F, S, TE>(_)
where
         F: Future<Output = Result<S, ProtoError>> + 'static + Send + Unpin,
         S: DnsRequestSender + 'static,
         TE: Time + Unpin;
Expand description

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.
