MX records cause type A additional section processing for the host
specified by EXCHANGE.  The use of MX RRs is explained in detail in
[RFC-974].

Methods

impl MX

pub fn new(preference: u16, exchange: Name) -> MX

Constructs a new MX RData

Arguments

• preference - weight of this MX record as opposed to others, lower values have the higher preference
• exchange - Name labels for the mail server

Returns

A new MX RData for use in a Resource Record

pub fn preference(&self) -> u16

RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987

PREFERENCE      A 16 bit integer which specifies the preference given to
                this RR among others at the same owner.  Lower values
                are preferred.

pub fn exchange(&self) -> &Name

RFC 1035, DOMAIN NAMES - IMPLEMENTATION AND SPECIFICATION, November 1987

EXCHANGE        A <domain-name> which specifies a host willing to act as
                a mail exchange for the owner name.
