Struct nex_packet::dns::MutableDnsResponsePacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableDnsResponsePacket<'a>

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

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

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

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

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

Maps from a MutableDnsResponsePacket to a DnsResponsePacket

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

Maps from a MutableDnsResponsePacket 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 populate(&mut self, packet: &DnsResponse)

Populates a DnsResponsePacket using a DnsResponse structure

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)

pub fn set_name_tag(&mut self, val: u16be)

Set the name_tag field. This field is always stored big-endian within the struct, but this mutator wants host order.

pub fn set_rtype(&mut self, val: DnsType)

Set the value of the rtype field.

pub fn set_rclass(&mut self, val: DnsClass)

Set the value of the rclass field.

pub fn set_ttl(&mut self, val: u32be)

Set the ttl field. This field is always stored big-endian within the struct, but this mutator wants host order.

pub fn set_data_len(&mut self, val: u16be)

Set the data_len field. This field is always stored big-endian within the struct, but this mutator wants host order.

pub fn get_data_raw_mut(&mut self) -> &mut [u8]

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

pub fn set_data(&mut self, vals: &[u8])

Set the value of the data field (copies contents)

pub fn set_payload(&mut self, vals: &[u8])

Set the value of the payload field (copies contents)

Trait Implementations

impl<'p> Debug for MutableDnsResponsePacket<'p>

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

Formats the value using the given formatter.

impl<'p> FromPacket for MutableDnsResponsePacket<'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> MutablePacket for MutableDnsResponsePacket<'a>

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

Retrieve the underlying, mutable, buffer for the packet.

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

Retrieve the mutable payload for the packet.

fn clone_from<T>(&mut self, other: &T)

where T: Packet,

Initialize this packet by cloning another.

impl<'a> Packet for MutableDnsResponsePacket<'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 MutableDnsResponsePacket<'a>

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for MutableDnsResponsePacket<'p>

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