Struct trust_dns::op::Edns

pub struct Edns { /* fields omitted */ }

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

Methods

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 dnssec_ok(&self) -> bool

Specifies that DNSSec is supported for this Client or Server

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 set_rcode_high(&mut self, rcode_high: u8)

Set the high order bits for the result code.

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

Set the EDNS version

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

Set to true if DNSSec is supported

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

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)

Set the specified EDNS option

Trait Implementations

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 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<'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

Performs the conversion.

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 PartialEq<Edns> for Edns

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Edns) -> bool

This method tests for !=.
