Struct DomainName 

pub struct DomainName(/* private fields */);

A domain name to look up.

The constructor checks the shape only. A name that no registry holds is a lookup that finds nothing, not a value this type refuses.

Implementations

impl DomainName

pub const MAX_BYTES: usize = 253

The longest a domain name can be, in bytes.

pub fn new(value: impl Into<String>) -> Result<Self, ValidationError>

Wraps a domain name.

The name is lowercased, and one trailing dot is removed.

Errors

Returns ValidationError::EmptyDomain for an empty name, and ValidationError::InvalidDomain when the name cannot be a domain name.

pub fn as_str(&self) -> &str

Returns the name, lowercased and without a trailing dot.

impl Ord for DomainName

fn cmp(&self, other: &DomainName) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn eq(&self, other: &DomainName) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for DomainName

fn partial_cmp(&self, other: &DomainName) -> 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.
