Struct hickory_proto::op::Edns

pub struct Edns { /* private fields */ }

Edns implements the higher level concepts for working with extended dns as it is used to create or be created from OPT record data.

Implementations

impl Edns

pub fn new() -> Self

Creates a new extended DNS object.

pub fn rcode_high(&self) -> u8

The high order bytes for the response code in the DNS Message

pub fn version(&self) -> u8

Returns the EDNS version

pub fn dnssec_ok(&self) -> bool

Specifies that DNSSEC is supported for this Client or Server

pub fn z_flags(&self) -> u16

Returns the Z flags. Should be ignored by receivers. Only the low 15 bits are significant. The high bit is always returned as zero.

pub fn max_payload(&self) -> u16

Maximum supported size of the DNS payload

pub fn option(&self, code: EdnsCode) -> Option<&EdnsOption>

Returns the Option associated with the code

pub fn options(&self) -> &OPT

Returns the options portion of EDNS

pub fn options_mut(&mut self) -> &mut OPT

Returns a mutable options portion of EDNS

pub fn set_rcode_high(&mut self, rcode_high: u8) -> &mut Self

Set the high order bits for the result code.

pub fn set_version(&mut self, version: u8) -> &mut Self

Set the EDNS version

pub fn set_dnssec_ok(&mut self, dnssec_ok: bool) -> &mut Self

Set to true if DNSSEC is supported

pub fn set_z_flags(&mut self, z: u16) -> &mut Self

Set the Z flags. Should be set to zero by senders. Only the low 15 bits are significant. The high bit is ignored.

pub fn set_max_payload(&mut self, max_payload: u16) -> &mut Self

Set the maximum payload which can be supported From RFC 6891: Values lower than 512 MUST be treated as equal to 512

pub fn set_option(&mut self, option: EdnsOption)

👎Deprecated: Please use options_mut().insert() to modify

Set the specified EDNS option

Trait Implementations

impl BinEncodable for Edns

fn emit(&self, encoder: &mut BinEncoder<'_>) -> ProtoResult<()>

Write the type to the stream

fn to_bytes(&self) -> ProtoResult<Vec<u8>>

Returns the object in binary form

impl Clone for Edns

fn clone(&self) -> Edns

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Edns

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

Formats the value using the given formatter.

impl Default for Edns

fn default() -> Self

Returns the “default value” for a type.

impl Display for Edns

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

Formats the value using the given formatter.

impl<'a> From<&'a Edns> for Record

fn from(value: &'a Edns) -> Self

This returns a Resource Record that is formatted for Edns(0). Note: the rcode_high value is only part of the rcode, the rest is part of the base

impl<'a> From<&'a Record> for Edns

fn from(value: &'a Record) -> Self

Converts to this type from the input type.

impl PartialEq for Edns

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