Struct Expire

pub struct Expire(/* private fields */);

Option data for the Expire EDNS option.

The option’s data consists of an optional u32. The value is omitted if the option is added to a query to request it being included by the server in an answer. In this answer the value should be present and indicates the expire time of the zone on the server.

See RFC 7314 for details.

Implementations

impl Expire

pub fn new(expire: Option<u32>) -> Self

Creates a new expire option with the given optional expire value.

pub fn expire(self) -> Option<u32>

Returns the content of the optional expire value.

pub fn parse<Octs: AsRef<[u8]>>( parser: &mut Parser<'_, Octs>, ) -> Result<Self, ParseError>

Parses a value from its wire format.

Trait Implementations

impl Clone for Expire

fn clone(&self) -> Expire

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComposeOptData for Expire

fn compose_len(&self) -> u16

fn compose_option<Target: OctetsBuilder + ?Sized>( &self, target: &mut Target, ) -> Result<(), Target::AppendError>

impl Debug for Expire

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

Formats the value using the given formatter.

impl Display for Expire

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

Formats the value using the given formatter.

impl<Octs, Name> From<Expire> for AllOptData<Octs, Name>

fn from(value: Expire) -> Self

Converts to this type from the input type.

impl Hash for Expire

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 OptData for Expire

fn code(&self) -> OptionCode

Returns the option code associated with this option.

impl Ord for Expire

fn cmp(&self, other: &Expire) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a, Octs: AsRef<[u8]>> ParseOptData<'a, Octs> for Expire

fn parse_option( code: OptionCode, parser: &mut Parser<'a, Octs>, ) -> Result<Option<Self>, ParseError>

Parses the option code data.

impl PartialEq for Expire

fn eq(&self, other: &Expire) -> 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 Expire

fn partial_cmp(&self, other: &Expire) -> 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.
