Struct NameRef 

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

Zero-copy DNS name reference into a message buffer.

Implementations

impl<'a> NameRef<'a>

pub fn try_parse( message: &'a [u8], offset: usize, ) -> Result<(Self, usize), ParseError>

Parses a name starting at offset in message. Returns the NameRef and the number of bytes consumed at the inline position (i.e. how far to advance the parser past this name in the original section — not how long the fully-resolved name is).

pub fn labels(&self) -> NameLabels<'a>

Returns an iterator over the labels of this name, following pointers with a bounded hop count.

pub const fn start(&self) -> u16

Returns the byte offset at which this name begins in the message.

pub fn equals_ignoring_case(&self, other: &NameRef<'_>) -> bool

Compares two names case-insensitively (mDNS rule, RFC 6762 §16).

Trait Implementations

impl<'a> Clone for NameRef<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for NameRef<'a>

impl<'a> Debug for NameRef<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for NameRef<'a>

impl<'a> Hash for NameRef<'a>

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

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<'a> PartialEq for NameRef<'a>

fn eq(&self, other: &NameRef<'a>) -> 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.
