Module xfer

DNS high level transit implimentations.

Primarily there are two types in this module of interest, the DnsMultiplexer type and the DnsHandle type. DnsMultiplexer can be thought of as the state machine responsible for sending and receiving DNS messages. DnsHandle is the type given to API users of the hickory-proto library to send messages into the DnsMultiplexer for delivery. Finally there is the DnsRequest type. This allows for customizations, through DnsRequestOptions, to the delivery of messages via a DnsMultiplexer.

TODO: this module needs some serious refactoring and normalization.

Modules

• dns_handle
  DnsHandle types perform conversions of the raw DNS messages before sending the messages on the specified streams.
• dns_multiplexer
  DnsMultiplexer and associated types implement the state machines for sending DNS messages while using the underlying streams.
• dns_request
  DnsRequest wraps a Message and associates a set of DnsRequestOptions for specifying different transfer options.
• dns_response
  DnsResponse wraps a Message and any associated connection details
• dnssec_dns_handlednssec
  The DnssecDnsHandle is used to validate all DNS responses for correct DNSSEC signatures.
• retry_dns_handle
  RetryDnsHandle allows for DnsQueries to be reattempted on failure

Structs

• BufDnsRequestStreamHandle
  Used for associating a name_server to a DnsRequestStreamHandle
• BufDnsStreamHandle
  A buffering stream bound to a SocketAddr
• DnsExchange
  This is a generic Exchange implemented over multiplexed DNS connection providers.
• DnsExchangeBackground
  This background future is responsible for driving all network operations for the DNS protocol.
• DnsExchangeConnect
  A wrapper for a future DnsExchange connection.
• DnsExchangeSend
  A Stream that will resolve to Responses after sending the request
• FirstAnswerFuture
  See FirstAnswer::first_answer
• OneshotDnsRequest
  A OneshotDnsRequest creates a channel for a response to message
• SerialMessage
  A DNS message in serialized form, with either the target address or source address

Enums

• DnsResponseReceiver
  A Stream that wraps a oneshot::Receiver<Stream> and resolves to items in the inner Stream
• Protocol
  The protocol on which a NameServer should be communicated with

Traits

• DnsClientStream
  A non-multiplexed stream of Serialized DNS messages
• DnsRequestSender
  Types that implement this are capable of sending a serialized DNS message on a stream
• FirstAnswer
  Helper trait to convert a Stream of dns response into a Future

Type Aliases

• StreamReceiver
  Receiver handle for peekable fused SerialMessage channel
