Struct address::domain::Domain

pub struct Domain { /* fields omitted */ }

Represents a domain name.

Methods

impl Domain

pub fn get_localhost() -> Self

Gets the localhost domain.

use address::domain::Domain;

assert_eq!(Domain::get_localhost().to_string(), "localhost");

impl Domain

pub const MAX_LABEL_LENGTH: usize

The maximum length of a domain label.

pub const MAX_DOMAIN_LENGTH: usize

The maximum length of a domain name.

pub fn is_valid_label(label: &[u8]) -> bool

Checks if the domain label is valid. This function is case insensitive.

use address::domain::Domain;

assert!(!Domain::is_valid_label("".as_bytes()));
assert!(Domain::is_valid_label("a".as_bytes()));
assert!(Domain::is_valid_label("A".as_bytes()));
assert!(Domain::is_valid_label("0".as_bytes()));
assert!(!Domain::is_valid_label("a-".as_bytes()));
assert!(!Domain::is_valid_label("-a".as_bytes()));
assert!(Domain::is_valid_label("a-b".as_bytes()));

pub fn is_valid_domain(name: &[u8]) -> bool

Checks if the domain name is valid. This function is case-insensitive.

use address::domain::Domain;

assert!(!Domain::is_valid_domain("".as_bytes()));
assert!(Domain::is_valid_domain("a".as_bytes()));
assert!(!Domain::is_valid_domain("a.".as_bytes()));
assert!(!Domain::is_valid_domain(".a".as_bytes()));
assert!(Domain::is_valid_domain("a.b".as_bytes()));

impl Domain

pub fn name(&self) -> &String

Gets the name.

pub fn host(self) -> Host

Gets the host.
