Struct nex_packet::dns::DnsResponsePacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> DnsResponsePacket<'a>

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

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

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

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

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

Maps from a DnsResponsePacket to a DnsResponsePacket

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

Maps from a DnsResponsePacket to a DnsResponsePacket 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: &DnsResponse) -> usize

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

pub fn get_name_tag(&self) -> u16be

Get the name_tag field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_rtype(&self) -> DnsType

Get the value of the rtype field

pub fn get_rclass(&self) -> DnsClass

Get the value of the rclass field

pub fn get_ttl(&self) -> u32be

Get the ttl field. This field is always stored big-endian within the struct, but this accessor returns host order.

pub fn get_data_len(&self) -> u16be

Get the data_len field. This field is always stored big-endian within the struct, but this accessor returns host order.

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

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

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

Get the value of the data field (copies contents)

Trait Implementations

impl<'p> Debug for DnsResponsePacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for DnsResponsePacket<'p>

type T = DnsResponse

The type of the packet to convert from.

fn from_packet(&self) -> DnsResponse

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

impl<'a> Packet for DnsResponsePacket<'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 DnsResponsePacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for DnsResponsePacket<'p>

fn eq(&self, other: &DnsResponsePacket<'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.
