Struct MutableDnsQueryPacket

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

A structure enabling manipulation of on the wire packets

Implementations

impl<'a> MutableDnsQueryPacket<'a>

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

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

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

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

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

Maps from a MutableDnsQueryPacket to a DnsQueryPacket

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

Maps from a MutableDnsQueryPacket 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 populate(&mut self, packet: &DnsQuery)

Populates a DnsQueryPacket using a DnsQuery structure

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

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

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

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

Set the value of the qname field (copies contents)

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

Set the value of the qtype field.

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

Set the value of the qclass field.

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

Set the value of the payload field (copies contents)

Trait Implementations

impl<'p> Debug for MutableDnsQueryPacket<'p>

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

Formats the value using the given formatter.

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

fn packet_size(&self) -> usize

Get the calculated size of the packet.

impl<'p> PartialEq for MutableDnsQueryPacket<'p>

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