Struct HeaderSection

pub struct HeaderSection { /* private fields */ }

The complete header section of a DNS message.

Consists of a Header and a HeaderCounts.

Implementations

impl HeaderSection

Creation and Conversion

pub fn new() -> Self

Creates a new empty header section.

pub fn for_message_slice(s: &[u8]) -> &HeaderSection

Creates a reference from the bytes slice of a message.

Panics

This function panics if the size of the bytes slice is smaller than the header section.

pub fn for_message_slice_mut(s: &mut [u8]) -> &mut HeaderSection

Creates a mutable reference from the bytes slice of a message.

Panics

This function panics if the size of the bytes slice is smaller than the header section.

pub fn as_slice(&self) -> &[u8]

Returns a reference to the underlying bytes slice.

impl HeaderSection

Access to Header and Counts

pub fn header(&self) -> &Header

Returns a reference to the header.

pub fn header_mut(&mut self) -> &mut Header

Returns a mutable reference to the header.

pub fn counts(&self) -> &HeaderCounts

Returns a reference to the header counts.

pub fn counts_mut(&mut self) -> &mut HeaderCounts

Returns a mutable reference to the header counts.

Trait Implementations

impl Clone for HeaderSection

fn clone(&self) -> HeaderSection

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compose for HeaderSection

fn compose_len(&self) -> usize

Returns the number of bytes this value will need without compression.

fn compose<B: BufMut>(&self, buf: &mut B)

Appends the uncompressed representation of this value to buf.

impl Debug for HeaderSection

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

Formats the value using the given formatter.

impl Default for HeaderSection

fn default() -> HeaderSection

Returns the “default value” for a type.

impl Parse for HeaderSection

type Err = ShortBuf

The type of an error returned when parsing fails.

fn parse(parser: &mut Parser) -> Result<Self, Self::Err>

Extracts a value from the beginning of parser.

fn skip(parser: &mut Parser) -> Result<(), Self::Err>

Skips over a value of this type at the beginning of parser.

impl PartialEq for HeaderSection

fn eq(&self, other: &HeaderSection) -> 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.
