Struct DnsExchange

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§

§

impl DnsExchange

pub fn from_stream<S, TE>( stream: S, ) -> (DnsExchange, 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

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

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

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.

pub fn error<F, S, TE>(error: ProtoError) -> 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 that returns an error immediately.
