Type Alias domain::base::opt::algsig::Dhu

pub type Dhu<Octs> = Understood<DhuVariant, Octs>;

A type alias for the DHU option.

Aliased Type

struct Dhu<Octs> { /* private fields */ }

Implementations

impl<Variant> Understood<Variant, [u8]>

pub fn from_slice(slice: &[u8]) -> Result<&Self, ParseError>

Creates a new value from an octets slice.

Returns an error if the slice does not contain a value in wire format or is longer than 65,535 octets.

pub unsafe fn from_slice_unchecked(slice: &[u8]) -> &Self

Creates a new value from an octets slice without checking.

Safety

The caller needs to make sure that the slice contains a sequence of 16 bit values that is no longer than 65,535 octets.

impl<Variant, Octs: AsRef<[u8]>> Understood<Variant, Octs>

pub fn parse<'a, Src: Octets<Range<'a> = Octs> + ?Sized>( parser: &mut Parser<'a, Src>, ) -> Result<Self, ParseError>

Parses a value from its wire format.

impl<Variant, Octs: ?Sized> Understood<Variant, Octs>

pub fn as_octets(&self) -> &Octs

Returns a reference to the underlying octets.

pub fn into_octets(self) -> Octs

where Octs: Sized,

Converts a value into its underlying octets.

pub fn as_slice(&self) -> &[u8]

where Octs: AsRef<[u8]>,

Returns the data as an octets slice.

pub fn for_slice(&self) -> &Understood<Variant, [u8]>

where Octs: AsRef<[u8]>,

Returns a reference to a value over an octets slice.

pub fn iter(&self) -> SecAlgsIter<'_>

where Octs: AsRef<[u8]>,

Returns an iterator over the algorithms in the data.

impl<Variant, Octs> Understood<Variant, Octs>

pub fn from_octets(octets: Octs) -> Result<Self, ParseError>

where Octs: AsRef<[u8]>,

Creates a new value from an octets sequence.

Returns an error if the slice does not contain a value in wire format or is longer than 65,535 octets.

pub unsafe fn from_octets_unchecked(octets: Octs) -> Self

Creates a new value from an octets sequence without checking.

Safety

The caller needs to make sure that the slice contains a sequence of 16 bit values that is no longer than 65,535 octets.

pub fn from_sec_algs( sec_algs: impl IntoIterator<Item = SecAlg>, ) -> Result<Self, BuildDataError>

where Octs: FromBuilder, <Octs as FromBuilder>::Builder: EmptyBuilder,

Creates a new value from a sequence of algorithms.

The operation will fail if the iterator returns more than 32,767 algorithms.
