Struct Header 

pub struct Header {
    pub id: u16,
    pub qr: Qr,
    pub op: OpCode,
    pub authoritative: bool,
    pub truncated: bool,
    pub recursion_desired: bool,
    pub recursion_available: bool,
    pub rcode: RCode,
}

Represents a message header.

Fields

id: u16

Transaction ID; corresponding replies will have the same ID.

qr: Qr

Query or response

op: OpCode

Kind of query

authoritative: bool

In a response, indicates that the responding name server is an authority for the domain name in question section.

truncated: bool

Indicates whether the message was truncated due to length greater than that permitted on the transmission channel.

recursion_desired: bool

In a query, directs the name server to pursue the query recursively.

recursion_available: bool

In a response, indicates whether recursive queries are available on the name server.

rcode: RCode

Response code

Implementations

impl Header

pub fn new() -> Header

Constructs a new Header with a random id value.

pub fn with_id(id: u16) -> Header

Constructs a new Header with the given id value.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Header

impl Eq for Header

impl StructuralPartialEq for Header
