Struct OPT

pub struct OPT<'a> {
    pub opt_codes: Vec<OPTCode<'a>>,
    pub udp_packet_size: u16,
    pub version: u8,
}

OPT is a pseudo-rr used to carry control information
If an OPT record is present in a received request, responders MUST include an OPT record in their respective responses.
OPT RRs MUST NOT be cached, forwarded, or stored in or loaded from master files.

There must be only one OPT record in the message. If a query message with more than one OPT RR is received, a FORMERR (RCODE=1) MUST be returned.

Fields

opt_codes: Vec<OPTCode<'a>>

The variable part of this OPT RR

udp_packet_size: u16

UDP packet size supported by the responder

version: u8

EDNS version supported by the responder

Implementations

impl<'a> OPT<'a>

pub fn into_owned<'b>(self) -> OPT<'b>

Transforms the inner data into its owned type

Trait Implementations

impl<'a> Clone for OPT<'a>

fn clone(&self) -> OPT<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for OPT<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for OPT<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for OPT<'a>

fn eq(&self, other: &OPT<'a>) -> 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.
