Struct Ref 

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

Parsed resource record (zero-copy view into a message). Stores the full message reference so type-specific rdata parsers can resolve compression pointers inside record data.

Implementations

impl<'a> Ref<'a>

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

Parses a single resource record from message at offset. Returns the record and the next offset to parse from.

pub const fn name(&self) -> &NameRef<'a>

Returns the owner name of this record.

pub const fn rtype(&self) -> ResourceType

Returns the resource record type.

pub const fn rclass(&self) -> ResourceClass

Returns the resource record class.

pub const fn cache_flush(&self) -> bool

Returns true if the mDNS cache-flush bit was set on this record.

pub const fn ttl(&self) -> u32

Returns the time-to-live value in seconds.

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

Raw rdata slice borrowed from the message.

pub fn rdata_view(&self) -> Result<Rdata<'a>, ParseError>

Interpret this record’s rdata, dispatching by Self::rtype. typed parsers now respect rdata_len so a malformed RDLENGTH cannot let a name (PTR/SRV) consume bytes past its declared boundary, and oversize A/AAAA rdata is rejected explicitly.

Trait Implementations

impl<'a> Clone for Ref<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Ref<'a>

impl<'a> Debug for Ref<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Ref<'a>

impl<'a> PartialEq for Ref<'a>

fn eq(&self, other: &Ref<'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.
