Struct domain::rdata::svcb::value::NoDefaultAlpn

pub struct NoDefaultAlpn;

A signal to not include the service’s default ALPNs in the ALPN set.

For each service that uses SVCB, a set of default Alpn protocols is defined. This set will be included even if they are not explicitely provided via the ALPN value. The no-default-alpn value can be used to signal that they should not be included.

This value is always empty.

Implementations

impl NoDefaultAlpn

pub fn parse<Src: Octets + ?Sized>( _parser: &mut Parser<'_, Src>, ) -> Result<Self, ParseError>

Parses a no-default-alpn value from its wire-format.

Trait Implementations

impl Clone for NoDefaultAlpn

fn clone(&self) -> NoDefaultAlpn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComposeSvcParamValue for NoDefaultAlpn

fn compose_len(&self) -> u16

Returns the length of the composed value.

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

Appends the wire format of the value to the end of target.

impl Debug for NoDefaultAlpn

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

Formats the value using the given formatter.

impl Display for NoDefaultAlpn

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

Formats the value using the given formatter.

impl<Octs> From<NoDefaultAlpn> for AllValues<Octs>

fn from(p: NoDefaultAlpn) -> Self

Converts to this type from the input type.

impl Hash for NoDefaultAlpn

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<'a, Octs: Octets + ?Sized> ParseSvcParamValue<'a, Octs> for NoDefaultAlpn

fn parse_value( key: SvcParamKey, parser: &mut Parser<'a, Octs>, ) -> Result<Option<Self>, ParseError>

Parse a parameter value from wire format.

impl PartialEq for NoDefaultAlpn

fn eq(&self, other: &NoDefaultAlpn) -> 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 SvcParamValue for NoDefaultAlpn

fn key(&self) -> SvcParamKey

Returns the parameter key of the value.

impl Copy for NoDefaultAlpn
