Struct Mx

pub struct Mx<N = ParsedDname> { /* private fields */ }

Mx record data.

The Mx record specifies a host willing to serve as a mail exchange for the owner name.

The Mx record type is defined in RFC 1035, section 3.3.9.

Implementations

impl<N> Mx<N>

pub fn new(preference: u16, exchange: N) -> Self

Creates a new Mx record data from the components.

pub fn preference(&self) -> u16

The preference for this record.

Defines an order if there are several Mx records for the same owner. Lower values are preferred.

pub fn exchange(&self) -> &N

The name of the host that is the exchange.

impl<N: Hash> Hash for Mx<N>

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<N: Ord> Ord for Mx<N>

fn cmp(&self, other: &Mx<N>) -> 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<N: Parse> Parse for Mx<N>

where N::Err: From<ShortBuf>,

type Err = <N as Parse>::Err

The type of an error returned when parsing fails.

fn parse(parser: &mut Parser) -> Result<Self, Self::Err>

Extracts a value from the beginning of parser.

fn skip(parser: &mut Parser) -> Result<(), Self::Err>

Skips over a value of this type at the beginning of parser.

impl<N: PartialEq> PartialEq for Mx<N>

fn eq(&self, other: &Mx<N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&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.
