Represents a header including flag fields and record counts

Fields

id: u16

Random ID for associating responses with requests

direction: Direction

Is the message a request or the associated response

opcode: Opcode

What is the message function, e.g query, reverse DNS query

authoritative: bool

truncation: bool

recursion_desired: bool

recursion_available: bool

valid_zeroes: bool

response: ResponseCode

Status of the request or response

question_count: u16

Number of questions being made, should be the same in both the request and response

answer_record_count: u16

authority_record_count: u16

additional_record_count: u16

Implementations

impl DNSHeader

pub fn to_bytes(&self) -> [u8; 12]

Serialise a header memory structure back into bytes for putting on the wire

pub fn new_request(id: u16, questions: Option<u16>) -> DNSHeader

Trait Implementations

impl Clone for DNSHeader

fn clone(&self) -> DNSHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DNSHeader

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

Formats the value using the given formatter.

impl Ord for DNSHeader

fn cmp(&self, other: &DNSHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DNSHeader

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for DNSHeader

fn partial_cmp(&self, other: &DNSHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
