[][src]Struct trust_dns_proto::xfer::DnsExchange

#[must_use = "futures do nothing unless polled"]
pub struct DnsExchange<S, R> where
    S: DnsRequestSender<DnsResponseFuture = R>,
    R: Future<Output = Result<DnsResponse, ProtoError>> + 'static + Send + Unpin
{ /* fields omitted */ }

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.

Methods

impl<S, R> DnsExchange<S, R> where
    S: DnsRequestSender<DnsResponseFuture = R>,
    R: Future<Output = Result<DnsResponse, ProtoError>> + 'static + Send + Unpin
[src]

pub fn from_stream(stream: S) -> (Self, DnsRequestStreamHandle<R>)[src]

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(
    stream: S,
    receiver: UnboundedReceiver<OneshotDnsRequest<R>>
) -> Self
[src]

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

pub fn connect<F>(
    connect_future: F
) -> (DnsExchangeConnect<F, S, R>, DnsRequestStreamHandle<R>) where
    F: Future<Output = Result<S, ProtoError>> + 'static + Send + Unpin
[src]

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

The connect_future should be lazy.
