Struct QuestionRef 

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

A parsed DNS question (zero-copy reference into a message buffer).

Implementations

impl<'a> QuestionRef<'a>

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

Parse a question starting at offset in message. Returns the question and the next offset to continue parsing from.

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

Returns the question’s name.

pub const fn qtype(&self) -> ResourceType

Returns the question type.

pub const fn qclass(&self) -> ResourceClass

Returns the question class (with unicast-response bit stripped).

pub const fn unicast_response_requested(&self) -> bool

true if the unicast-response bit (RFC 6762 §5.4) was set on this question’s class field.

Trait Implementations

impl<'a> Clone for QuestionRef<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for QuestionRef<'a>

impl<'a> Debug for QuestionRef<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for QuestionRef<'a>

impl<'a> Hash for QuestionRef<'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 QuestionRef<'a>

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