Implementations

impl Rcode

pub fn value(self) -> u16

pub fn low(self) -> u8

pub fn high(self) -> u8

pub fn has_extended_bits(self) -> bool

pub fn from_parts(high: u8, low: u8) -> Self

pub fn to_str(self) -> &'static str

Transforms the response code into the human message

Trait Implementations

impl Clone for Rcode

fn clone(&self) -> Rcode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rcode

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

Formats the value using the given formatter.

impl Default for Rcode

fn default() -> Rcode

Returns the “default value” for a type.

impl Display for Rcode

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

Formats the value using the given formatter.

impl From<Rcode> for u16

fn from(rt: Rcode) -> Self

Converts to this type from the input type.

impl From<u16> for Rcode

fn from(value: u16) -> Self

Converts to this type from the input type.

impl Hash for Rcode

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 Rcode

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

impl PartialOrd for Rcode

fn partial_cmp(&self, other: &Rcode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for Rcode

impl Eq for Rcode

impl StructuralPartialEq for Rcode
