Struct Message

pub struct Message {
    pub header: Header,
    pub questions: Vec<Question>,
    pub answers: Vec<ResourceRecord>,
    pub authority: Vec<ResourceRecord>,
    pub additional: Vec<ResourceRecord>,
}

Basic DNS message format, used for both queries and responses.

    +---------------------+
    |        Header       |
    +---------------------+
    |       Question      | the question for the name server
    +---------------------+
    |        Answer       | RRs answering the question
    +---------------------+
    |      Authority      | RRs pointing toward an authority
    +---------------------+
    |      Additional     | RRs holding additional information

Implementations

impl Message

pub fn from_octets(octets: &[u8]) -> Result<Self, Error>

Errors

If the message cannot be parsed.

fn deserialise(buffer: &mut ConsumableBuffer<'_>) -> Result<Self, Error>

Errors

If the message cannot be parsed.

impl Message

pub fn to_octets(&self) -> Result<BytesMut, Error>

Errors

If the message is invalid (the Message type permits more states than strictly allowed).

fn serialise(&self, buffer: &mut WritableBuffer) -> Result<(), Error>

Errors

If the message is invalid (the Message type permits more states than strictly allowed).

impl Message

pub fn make_response(&self) -> Self

pub fn make_format_error_response(id: u16) -> Self

pub fn from_question(id: u16, question: Question) -> Self

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl Hash for Message

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Message

fn cmp(&self, other: &Message) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Message

fn eq(&self, other: &Message) -> 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 PartialOrd for Message

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Eq for Message
