Implementations

impl QClass

pub fn u16_to_qclass(value: u16) -> CDnsResult<QClass>

Converts u16 to enum QClass.

QCLASS fields appear in the question part of a query. QCLASS are a superset of CLASSes, hence all CLASSes are valid QCLASSes.

pub fn u16_to_class(value: u16) -> CDnsResult<QClass>

Converts u16 to enum QClass, but for the response part of a query.

Trait Implementations

impl Clone for QClass

fn clone(&self) -> QClass

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QClass

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

Formats the value using the given formatter.

impl Default for QClass

fn default() -> Self

Returns the “default value” for a type.

impl Display for QClass

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

Formats the value using the given formatter.

impl Hash for QClass

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 Into<u16> for QClass

fn into(self) -> u16

Converts this type into the (usually inferred) input type.

impl PartialEq for QClass

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

impl Copy for QClass

impl Eq for QClass
