Module op 

Operations to send with a Client or server, e.g. Query, Message, or UpdateMessage can be used together to either query or update resource records sets.

Modules

update_message

Update related operations for Messages

Structs

DnsRequest

A DNS request object

DnsRequestOptions

A set of options for expressing options to how requests should be treated

DnsResponse

A DNS response object

Edns

Edns implements the higher level concepts for working with extended dns as it is used to create or be created from OPT record data.

EdnsFlags

EDNS flags

Flags

All the flags of the request/response header

Header

Metadata for the Message struct.

LowerQuery

Identical to Query, except that the Name is guaranteed to be in lower case form.

Message

The basic request and response data structure, used for all DNS protocols.

MessageParts

Consumes Message giving public access to fields in Message so they can be destructured and taken by value

Query

Query struct for looking up resource records, basically a resource record without RDATA.

SerialMessage

A DNS message in serialized form, with either the target address or source address

Enums

MessageType

Message types are either Query (also Update) or Response

OpCode

Operation code for queries, updates, and responses

ResponseCode

The status code of the response to a query.

Constants

DEFAULT_RETRY_FLOOR

Default retry interval floor. This value is somewhat arbitrary, but is based on observed, real-world latencies and offers the chance to send three queries in a second to maximize the chance of a successful response in periods of high packet loss without overwhelming upstream servers.

Traits

EmitAndCount

A trait that defines types which can be emitted as a set, with the associated count returned.

UpdateMessage

To reduce errors in using the Message struct as an Update, this will do the call throughs to properly do that.

Functions

emit_message_parts

Emits the different sections of a message properly
