Struct Domain

pub struct Domain { /* private fields */ }

A basic data type for housing Internet domains.

Implementations

impl Domain

pub fn from(data: &str) -> Option<Domain>

Creates a Domain from an existing string. If it contains illegal characters, it will return None. All capital letters will have their case squashed. This type exists to ensure that valid domains are used across the library

pub fn as_string(&self) -> &str

Returns the Domain as a string

pub fn parent(&self) -> Option<Domain>

Returns the parent domain unless doing so would return a top-level domain, i.e. ‘.com’, in which case it returns None.

pub fn pop(&mut self) -> Result<(), LKCError>

Removes a level of subdomains from the item, working much like parent() except that the current object is modified. LKCError::ErrOutOfRange is returned if the call would result in the Domain object housing just a top-level domain, such as com.

pub fn push(&mut self, subdom: &str) -> Result<(), LKCError>

Adds a subdomain to the object

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 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.

impl PartialOrd for Domain

fn partial_cmp(&self, other: &Domain) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&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.
