pub struct DnsExchange { /* private fields */ }
Expand description

This is a generic Exchange implemented over multiplexed DNS connection providers.

The underlying DnsRequestSender is expected to multiplex any I/O connections. DnsExchange assumes that the underlying stream is responsible for this.

Implementations§

source§

impl DnsExchange

source

pub fn from_stream<S, TE>(stream: S) -> (Self, DnsExchangeBackground<S, TE>)where S: DnsRequestSender + 'static + Send + Unpin,

Initializes a TcpStream with an existing tcp::TcpStream.

This is intended for use with a TcpListener and Incoming.

Arguments
  • stream - the established IO stream for communication
source

pub fn from_stream_with_receiver<S, TE>( stream: S, receiver: Receiver<OneshotDnsRequest>, sender: BufDnsRequestStreamHandle ) -> (Self, DnsExchangeBackground<S, TE>)where S: DnsRequestSender + 'static + Send + Unpin,

Wraps a stream where a sender and receiver have already been established

source

pub fn connect<F, S, TE>(connect_future: F) -> DnsExchangeConnect<F, S, TE> where F: Future<Output = Result<S, ProtoError>> + 'static + Send + Unpin, S: DnsRequestSender + 'static + Send + Unpin, TE: Time + Unpin,

Returns a future, which itself wraps a future which is awaiting connection.

The connect_future should be lazy.
