Possible OPCODE values for a DNS packet, use to specify the type of operation.
RFC 1035: 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.

Variants

StandardQuery = 0

Normal query

InverseQuery = 1

Inverse query (query a name by IP)

ServerStatusRequest = 2

Server status request

Notify = 4

Notify query

Update = 5

Update query RFC 2136

Reserved = 6

Reserved opcode for future use

Trait Implementations

impl Clone for OPCODE

fn clone(&self) -> OPCODE

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OPCODE

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

Formats the value using the given formatter.

impl From<u16> for OPCODE

fn from(code: u16) -> Self

Converts to this type from the input type.

impl PartialEq for OPCODE

fn eq(&self, other: &OPCODE) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
