Enum DnsClass 

pub enum DnsClass {
    Internet,
    Any,
    Unknown(u16),
}

CLASS fields appear in resource records. The following CLASS mnemonics and values are defined:

• IN 1 the Internet
• CS 2 the CSNET class (Obsolete - used only for examples in some obsolete RFCs)
• CH 3 the CHAOS class
• HS 4 Hesiod [Dyer 87]

QCLASS fields appear in the question section of a query. QCLASS values are a superset of CLASS values; every CLASS is a valid QCLASS. In addition to CLASS values, the following QCLASSes are defined:

• * 255 any class

Implementations

impl DnsClass

pub fn new(value: u16) -> Self

pub fn num(&self) -> u16

pub fn read<const N: usize>(buf: &mut FixedBuf<N>) -> Result<Self, DnsError>

Errors

Returns an error when buf does not contain two bytes.

pub fn write<const N: usize>( &self, out: &mut FixedBuf<N>, ) -> Result<(), DnsError>

Errors

Returns an error when buf is full.

Trait Implementations

impl Clone for DnsClass

fn clone(&self) -> DnsClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsClass

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

Formats the value using the given formatter.

impl Hash for DnsClass

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 PartialEq for DnsClass

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