Struct Ptr 

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

Parsed PTR record rdata.

Implementations

impl<'a> Ptr<'a>

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

Parses a PTR record’s rdata. message is the full DNS message so compression pointers can resolve; rdata_offset is the start of the rdata bytes within it; rdata_len is the declared RDLENGTH.

the inline portion of the encoded name (label bytes plus any initial compression pointer) MUST fit within the declared rdata_len. Without this check a record advertising a short rdlength could let inline labels run past the declared boundary and consume bytes from the next record, corrupting downstream conflict-routing, known-answer suppression, and cache decisions.

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

Returns the target name.

Trait Implementations

impl<'a> Clone for Ptr<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for Ptr<'a>

impl<'a> Debug for Ptr<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Ptr<'a>

impl<'a> Hash for Ptr<'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 Ptr<'a>

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