Struct Edns 

pub struct Edns { /* private fields */ }

Available on crate feature dns only.

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() -> Edns

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 flags(&self) -> &EdnsFlags

Returns the EdnsFlags portion of EDNS

pub fn flags_mut(&mut self) -> &mut EdnsFlags

Returns a mutable reference to the EdnsFlags

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 Edns

Set the high order bits for the result code.

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

Set the EDNS version

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

Set to true if DNSSEC is supported

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

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<'_>) -> Result<(), ProtoError>

Write the type to the stream

fn to_bytes(&self) -> Result<Vec<u8>, ProtoError>

Returns the object in binary form

impl Clone for Edns

fn clone(&self) -> Edns

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Default for Edns

fn default() -> Edns

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) -> Record

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) -> Edns

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.
