Struct DnsQuestion 

pub struct DnsQuestion {
    pub qname: DnsName,
    pub qtype: u16,
    pub qclass: u16,
}

A DNS question record.

Fields

qname: DnsName

The domain name being queried.

qtype: u16

The query type (e.g., A=1, AAAA=28, MX=15).

qclass: u16

The query class (typically IN=1). For mDNS, bit 15 is the unicast-response flag.

Implementations

impl DnsQuestion

pub fn new(qname: DnsName) -> Self

Create a new question with default type A and class IN.

pub fn from_name(name: &str) -> Result<Self, FieldError>

Create a question from a domain name string.

pub fn unicast_response(&self) -> bool

Whether this is an mDNS unicast-response question.

pub fn actual_class(&self) -> u16

Get the actual class (without the mDNS unicast-response bit).

pub fn set_unicast_response(&mut self, unicast: bool)

Set the mDNS unicast-response flag.

pub fn parse(packet: &[u8], offset: usize) -> Result<(Self, usize), FieldError>

Parse a question from wire format.

packet is the full DNS packet (for pointer decompression). offset is the start of the question record.

Returns the parsed question and bytes consumed.

pub fn build(&self) -> Vec<u8>

Build the question record without compression.

pub fn build_compressed( &self, current_offset: usize, compression_map: &mut HashMap<String, u16>, ) -> Vec<u8>

Build with DNS name compression.

pub fn summary(&self) -> String

Human-readable summary.

Trait Implementations

impl Clone for DnsQuestion

fn clone(&self) -> DnsQuestion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsQuestion

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

Formats the value using the given formatter.

impl Default for DnsQuestion

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DnsQuestion

fn eq(&self, other: &DnsQuestion) -> 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.
