Enum DnsOpCode 

pub enum DnsOpCode {
    Query,
    InverseQuery,
    Status,
    Reserved(u8),
}

OPCODE A four bit field that specifies kind of query in this message. This value is set by the originator of a query and copied into the response. The values are:

• 0 a standard query (QUERY)
• 1 an inverse query (IQUERY)
• 2 a server status request (STATUS)
• 3-15 reserved for future use

Implementations

impl DnsOpCode

pub fn new(value: u8) -> Self

pub fn num(&self) -> u8

Trait Implementations

impl Clone for DnsOpCode

fn clone(&self) -> DnsOpCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DnsOpCode

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

Formats the value using the given formatter.

impl Hash for DnsOpCode

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 PartialEq for DnsOpCode

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