Struct nex_packet::dns::DnsQueryPacket

pub struct DnsQueryPacket<'p> { /* private fields */ }

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> DnsQueryPacket<'a>

pub fn new<'p>(packet: &'p [u8]) -> Option<DnsQueryPacket<'p>>

Constructs a new DnsQueryPacket. If the provided buffer is less than the minimum required packet size, this will return None.

pub fn owned(packet: Vec<u8>) -> Option<DnsQueryPacket<'static>>

Constructs a new DnsQueryPacket. If the provided buffer is less than the minimum required packet size, this will return None. With this constructor the DnsQueryPacket will own its own data and the underlying buffer will be dropped when the DnsQueryPacket is.

pub fn to_immutable<'p>(&'p self) -> DnsQueryPacket<'p>

Maps from a DnsQueryPacket to a DnsQueryPacket

pub fn consume_to_immutable(self) -> DnsQueryPacket<'a>

Maps from a DnsQueryPacket to a DnsQueryPacket while consuming the source

pub const fn minimum_packet_size() -> usize

The minimum size (in bytes) a packet of this type can be. It’s based on the total size of the fixed-size fields.

pub fn packet_size(_packet: &DnsQuery) -> usize

The size (in bytes) of a DnsQuery instance when converted into a byte-array

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

Get the raw &u8 value of the qname field, without copying

pub fn get_qname(&self) -> Vec<u8>

Get the value of the qname field (copies contents)

pub fn get_qtype(&self) -> DnsType

Get the value of the qtype field

pub fn get_qclass(&self) -> DnsClass

Get the value of the qclass field

Trait Implementations

impl<'p> Debug for DnsQueryPacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for DnsQueryPacket<'p>

type T = DnsQuery

The type of the packet to convert from.

fn from_packet(&self) -> DnsQuery

Converts a wire-format packet to #[packet] struct format.

impl<'a> Packet for DnsQueryPacket<'a>

fn packet<'p>(&'p self) -> &'p [u8]

Retrieve the underlying buffer for the packet.

fn payload<'p>(&'p self) -> &'p [u8]

Retrieve the payload for the packet.

impl<'a> PacketSize for DnsQueryPacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for DnsQueryPacket<'p>

fn eq(&self, other: &DnsQueryPacket<'p>) -> 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.
