Enum Domain 

pub enum Domain {
    DomainName(DomainString),
    V4(Ipv4Addr),
    V6(Ipv6Addr),
    Tagged(String),
}

Domain part of a mailbox in a MAIL FROM address.

Variants

DomainName(DomainString)

A valid DNS domain name

V4(Ipv4Addr)

An IPv4 address literal, e.g. from [10.0.0.1]

V6(Ipv6Addr)

An IPv6 address literal, e.g. from [IPv6:::1]

Tagged(String)

A general/tagged address literal, e.g. from [future:something]. Stores the original "tag:literal" string; split on the first : when the tag or literal parts are needed individually.

Implementations

impl Domain

pub fn is_ascii(&self) -> bool

Returns true if the wire representation of this domain is pure ASCII.

DomainName is always normalized to ASCII punycode on the wire, so it is always considered ASCII here. IP address literals are inherently ASCII. Tagged literals are checked character-by-character.

Trait Implementations

impl Clone for Domain

fn clone(&self) -> Domain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Domain

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

Formats the value using the given formatter.

impl Display for Domain

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

Formats the value using the given formatter.

impl Hash for Domain

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 PartialEq for Domain

fn eq(&self, other: &Domain) -> 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.
