Enum DnsType

pub enum DnsType {
    A,
    AAAA,
    CNAME,
    MX,
    NS,
    PTR,
    SOA,
    TXT,
    ANY,
    Unknown(u16),
}

TYPE fields are used in resource records. Note that these types are a subset of QTYPEs.

https://datatracker.ietf.org/doc/html/rfc1035#section-3.2.2

A record type is defined to store a host’s IPv6 address. A host that has more than one IPv6 address must have more than one such record.

https://datatracker.ietf.org/doc/html/rfc3596#section-2

QTYPE fields appear in the question part of a query. QTYPES are a superset of TYPEs, hence all TYPEs are valid QTYPEs.

https://datatracker.ietf.org/doc/html/rfc1035#section-3.2.3

Variants

A

IPv4 address

AAAA

IPv6 address

CNAME

The canonical name for an alias

MX

Mail exchange

NS

Authoritative name server

PTR

Domain name pointer

SOA

Marks the start of a zone of authority

TXT

Text string

ANY

Unknown(u16)

Implementations

impl DnsType

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 a valid two-byte type code.

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

Errors

Returns an error when buf fills up.

Trait Implementations

impl Clone for DnsType

fn clone(&self) -> DnsType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsType

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

Formats the value using the given formatter.

impl Display for DnsType

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

Formats the value using the given formatter.

impl Hash for DnsType

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 Ord for DnsType

fn cmp(&self, other: &DnsType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DnsType

fn eq(&self, other: &DnsType) -> 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 PartialOrd for DnsType

fn partial_cmp(&self, other: &DnsType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
