Expand description

Defines the possible mechanisms.

Variants§

§

Redirect

Represents a Modifier of type redirect=
If this is present, the All mechanism should not be present.

§

A

Represents a Mechanism of type A

Possible Values:

a   
a/24  
a:example.com  
a:example.com/24  
§

MX

Represents a Mechanism of type MX
Possible values follow the same loy out as for A

§

Include

Represents a Mechanism of type Include

include:<domain>
§

IpV4

Represents a Mechanism of type ip4

Example Values:

ip4:192.168.11.0/24  
ip4:10.10.1.1
§

IpV6

Represents a Mechanism of type ip6

§

Ptr

Represents a Mechanism of type ptr

Note:

This is rarely use.

§

Exists

Represents a Mechanism of type exists

 ptr
 ptr:<domain>
§

All

Represents a Mechanism of type All

Implementations§

source§

impl Kind

source

pub fn is_redirect(&self) -> bool

Returns true if the mechanism is Redirect.

source

pub fn is_a(&self) -> bool

Returns true if the mechanism is A.

source

pub fn is_mx(&self) -> bool

Returns true if the mechanism is MX.

source

pub fn is_include(&self) -> bool

Returns true if the mechanism is Include.

source

pub fn is_ip(&self) -> bool

Returns true if it is of any ip. V4 or V6

Examples:
let ip4 = Kind::IpV4;
let ip6 = Kind::IpV6;
assert_eq!(ip4.is_ip_v4(), true);
assert_eq!(ip4.is_ip_v6(), false);
assert_eq!(ip4.is_ip(), true);
assert_eq!(ip6.is_ip_v6(), true);
assert_eq!(ip6.is_ip_v4(), false);
assert_eq!(ip6.is_ip(), true);
source

pub fn is_ip_v4(&self) -> bool

Returns true if the mechanism is IpV4.

source

pub fn is_ip_v6(&self) -> bool

Returns true if the mechanism is IpV6.

source

pub fn is_ptr(&self) -> bool

Returns true if the mechanism is Ptr.

source

pub fn is_exists(&self) -> bool

Returns true if the mechanism is Exists.

source

pub fn is_all(&self) -> bool

Returns true if the mechanism is All.

source

pub fn as_str(&self) -> &str

Returns a reference to the str for kind enums.

Examples:
let a = Kind::A;
let mx = Kind::MX;
assert_eq!(a.as_str(), "a");
assert_eq!(a.is_a(), true);
assert_eq!(mx.as_str(), "mx");
assert_eq!(mx.is_mx(), true);
