aa: AuthoritativeAnswer

The answer is authoritative.

tc: TrunCation

The packet has been truncated.

rd: RecursionDesired

The client desires recursion.

ra: RecursionAvailable

The server has recursion availbale.

Trait Implementations

impl Clone for Flags

fn clone(&self) -> Flags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Flags

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

Formats the value using the given formatter.

impl PartialEq<Flags> for Flags

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

impl TryFrom<u16> for Flags

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(n: u16) -> Result<Flags, <Flags as TryFrom<u16>>::Error>

Performs the conversion.
