Implementations

impl DnsResponsePacket

pub fn from_buf_mut(buf: &mut &[u8]) -> Option<Self>

Creates a new DnsResponsePacket from a mutable buffer.

pub fn get_ipv4(&self) -> Option<Ipv4Addr>

Returns the IPv4 address if the record type is A and data length is 4 bytes.

pub fn get_ipv6(&self) -> Option<Ipv6Addr>

Returns the IPv6 address if the record type is AAAA and data length is 16 bytes.

pub fn get_ip(&self) -> Option<IpAddr>

Returns the IP address based on the record type.

pub fn get_name(&self) -> Option<DnsName>

Returns the DNS name if the record type is CNAME, NS, or PTR.

pub fn get_txt_strings(&self) -> Option<Vec<String>>

Returns the TXT strings if the record type is TXT.

Trait Implementations

impl Clone for DnsResponsePacket

fn clone(&self) -> DnsResponsePacket

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsResponsePacket

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

Formats the value using the given formatter.

impl Packet for DnsResponsePacket

type Header = ()

fn from_buf(buf: &[u8]) -> Option<Self>

Parse from a byte slice.

fn from_bytes(bytes: Bytes) -> Option<Self>

Parse from raw bytes. (with ownership)

fn to_bytes(&self) -> Bytes

Serialize into raw bytes.

fn header(&self) -> Bytes

Get the header of the packet.

fn payload(&self) -> Bytes

Get the payload of the packet.

fn header_len(&self) -> usize

Get the length of the header.

fn payload_len(&self) -> usize

Get the length of the payload.

fn total_len(&self) -> usize

Get the total length of the packet (header + payload).

fn into_parts(self) -> (Self::Header, Bytes)

fn to_bytes_mut(&self) -> BytesMut

Convert the packet to a mutable byte buffer.

fn header_mut(&self) -> BytesMut

Get a mutable byte buffer for the header.

fn payload_mut(&self) -> BytesMut

impl PartialEq for DnsResponsePacket

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