Enum RRType

#[non_exhaustive]
#[repr(u16)]
pub enum RRType {
    A = 1,
    CNAME = 5,
    PTR = 12,
    HINFO = 13,
    TXT = 16,
    AAAA = 28,
    SRV = 33,
    NSEC = 47,
    ANY = 255,
}

DNS resource record types, stored as u16. Can do as u16 when needed.

See RFC 1035 section 3.2.2

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

A = 1

DNS record type for IPv4 address

CNAME = 5

DNS record type for Canonical Name

PTR = 12

DNS record type for Pointer

HINFO = 13

DNS record type for Host Info

TXT = 16

DNS record type for Text (properties)

AAAA = 28

DNS record type for IPv6 address

SRV = 33

DNS record type for Service

NSEC = 47

DNS record type for Negative Responses

ANY = 255

DNS record type for any records (wildcard)

Implementations

impl RRType

pub const fn from_u16(value: u16) -> Option<RRType>

Converts u16 into RRType if possible.

Trait Implementations

impl Clone for RRType

fn clone(&self) -> RRType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RRType

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

Formats the value using the given formatter.

impl Display for RRType

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

Formats the value using the given formatter.

impl Ord for RRType

fn cmp(&self, other: &RRType) -> 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 RRType

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

fn partial_cmp(&self, other: &RRType) -> 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.
