A two octet code which specifies the type of the query. TYPE fields are used in resource records. Note that these types are a subset of QTYPEs. QTYPE fields appear in the question part of a query. QTYPES are a superset of TYPEs, hence all TYPEs are valid QTYPEs.

Implementations

impl QType

pub fn ipaddr_match(&self, ip: &IpAddr) -> bool

pub fn u16_to_qtype(value: u16) -> CDnsResult<QType>

pub fn u16_to_type(value: u16) -> CDnsResult<QType>

Trait Implementations

impl Clone for QType

fn clone(&self) -> QType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QType

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

Formats the value using the given formatter.

impl Default for QType

fn default() -> Self

Returns the “default value” for a type.

impl Display for QType

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

Formats the value using the given formatter.

impl Hash for QType

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 QType

fn into(self) -> u16

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

impl PartialEq for QType

fn eq(&self, other: &QType) -> 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 QType

impl Eq for QType

impl StructuralPartialEq for QType
