Struct DomainRef 

pub struct DomainRef<'a> { /* private fields */ }

Available on crate feature net only.

Borrowed view into a domain-name byte slice.

The slice is contractually a validated Domain in presentation form (ASCII A-label) — invariants are enforced wherever DomainRef is constructed. Methods always treat the bytes as ASCII (and therefore valid UTF-8).

Useful for any context where you want a borrowed domain view without committing to an owned Domain allocation — e.g. iterating zero-copy slices out of a parent buffer, or pattern-matching against a transient header value.

PartialEq / Eq / Hash / Ord / PartialOrd are ASCII-case-insensitive per RFC 3986 §6.2.2.1 (and §3.2.2 host) — DomainRef("EXAMPLE.com") and DomainRef("example.com") compare and hash identically. Mirrors the owned Domain’s semantics so the two types stay interchangeable as collection keys.

Implementations

impl<'a> DomainRef<'a>

pub fn as_bytes(&self) -> &'a [u8]

Returns the raw bytes (always ASCII).

pub fn as_str(&self) -> &'a str

Returns the domain as a &str. ASCII bytes are valid UTF-8 by construction.

pub fn into_owned(self) -> Domain

Returns an owned Domain by copying the underlying bytes. Named into_owned (matching std::borrow::Cow::into_owned) so it doesn’t shadow the std ToOwned trait method.

pub fn as_unicode(&self) -> Cow<'a, str>

Available on crate feature idna only.

Returns the Unicode (display) form of the domain. See Domain::as_unicode for the contract.

Trait Implementations

impl<'a> Clone for DomainRef<'a>

fn clone(&self) -> DomainRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DomainRef<'a>

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

Formats the value using the given formatter.

impl Display for DomainRef<'_>

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

Formats the value using the given formatter.

impl<'a> From<&'a Domain> for DomainRef<'a>

fn from(d: &'a Domain) -> DomainRef<'a>

Converts to this type from the input type.

impl Hash for DomainRef<'_>

fn hash<H>(&self, state: &mut H)

where H: Hasher,

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 Ord for DomainRef<'_>

fn cmp(&self, other: &DomainRef<'_>) -> 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 clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DomainRef<'_>

fn eq(&self, other: &DomainRef<'_>) -> 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 DomainRef<'_>

fn partial_cmp(&self, other: &DomainRef<'_>) -> 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.
