pub struct Edns { /* private fields */ }
Expand description

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§

source§

impl Edns

source

pub fn new() -> Self

pub fn version(&self) -> u8

Returns the EDNS version

source

pub fn dnssec_ok(&self) -> bool

Specifies that DNSSEC is supported for this Client or Server

source

pub fn max_payload(&self) -> u16

Maximum supported size of the DNS payload

source

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

Returns the Option associated with the code

source

pub fn options(&self) -> &OPT

Returns the options portion of EDNS

source

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

Returns a mutable options portion of EDNS

source

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

Set the high order bits for the result code.

source

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

Set the EDNS version

source

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

Set to true if DNSSEC is supported

source

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

source

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

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

Set the specified EDNS option

Trait Implementations§

source§

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

source§

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

source§

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

source§

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

Converts to this type from the input type.
source§

impl PartialEq for Edns

source§

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
