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

#[must_use = "futures do nothing unless polled"]pub struct DnsExchange<R> where
    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.

Implementations

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

pub fn from_stream<S, TE>(stream: S) -> (Self, DnsExchangeBackground<S, R, TE>) where
    S: DnsRequestSender<DnsResponseFuture = R> + 'static + Send + Unpin
[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<S, TE>(
    stream: S,
    receiver: UnboundedReceiver<OneshotDnsRequest<R>>,
    sender: DnsRequestStreamHandle<R>
) -> (Self, DnsExchangeBackground<S, R, TE>) where
    S: DnsRequestSender<DnsResponseFuture = R> + 'static + Send + Unpin
[src]

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

pub fn connect<F, S, TE>(connect_future: F) -> DnsExchangeConnect<F, S, R, TE>

Notable traits for DnsExchangeConnect<F, S, R, TE>

impl<F, S, R, TE> Future for DnsExchangeConnect<F, S, R, TE> where
    F: Future<Output = Result<S, ProtoError>> + 'static + Send + Unpin,
    S: DnsRequestSender<DnsResponseFuture = R> + 'static + Send + Unpin,
    R: Future<Output = Result<DnsResponse, ProtoError>> + 'static + Send + Unpin,
    TE: Time + Unpin
type Output = Result<(DnsExchange<R>, DnsExchangeBackground<S, R, TE>), ProtoError>;
where
    F: Future<Output = Result<S, ProtoError>> + 'static + Send + Unpin,
    S: DnsRequestSender<DnsResponseFuture = R> + 'static + Send + Unpin,
    TE: Time + Unpin
[src]

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

The connect_future should be lazy.

Trait Implementations

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

impl<Resp> DnsHandle for DnsExchange<Resp> where
    Resp: Future<Output = Result<DnsResponse, ProtoError>> + 'static + Send + Unpin
[src]

type Response = DnsExchangeSend<Resp>

The associated response from the response future, this should resolve to the Response message
