Struct Ipv6Hint

pub struct Ipv6Hint<Octs: ?Sized>(/* private fields */);

The ‘ipv6hint’ service parameter value.

This values provides a list of IPv6 addresses that the client may use to connect to the endpoint. The value is intended to speed up connecting but not to replace the AAAA query to get the actual IPv6 addresses of the endpoint. That is, the client can start an AAAA query and at the same time connect to an IP address from the value. If the AAAA query doesn’t return this IP address, it may want to start again with an address from the response.

The type contains the value in its wire format which consists of the sequence of IPv6 addresses.

Implementations

impl<Octs> Ipv6Hint<Octs>

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

Creates a new value from octets without checking.

Safety

The caller has to ensure that octets contains a properly formated value of at most 65,535 octets.

impl Ipv6Hint<[u8]>

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

Creates a new value for a slice without checking.

Safety

The caller has to ensure that slice contains a properly formated value of at most 65,535 octets.

impl<Octs: ?Sized> Ipv6Hint<Octs>

pub fn as_octets(&self) -> &Octs

Returns a reference to the underlying octets sequence.

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

where Octs: AsRef<[u8]>,

Returns a slice of the underlying octets sequence.

impl<Octs: AsRef<[u8]> + ?Sized> Ipv6Hint<Octs>

pub fn iter(&self) -> Ipv6HintIter<'_, Octs>

Returns an iterator over the elements of the value.

impl<Octs: AsRef<[u8]>> Ipv6Hint<Octs>

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

Creates a new ipv6hint value from its content.

The function returns an error if octets doesn’t contain a correctly encoded value or if it is longer than 65,535 octets.

pub fn from_addrs( addrs: impl IntoIterator<Item = Ipv6Addr>, ) -> Result<Self, BuildValueError>

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

Creates a new value from a list of IPv6 addresses.

The function will fail if the iterator returns more than 16,383 addresses or if the octets builder to be used for building runs out of space.

impl Ipv6Hint<[u8]>

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

Creates a new ‘ipv6hint’ value from a slice of its content.

The function returns an error if slice doesn’t contain a correctly encoded value or if it is longer than 65,535 octets.

impl<Octs: AsRef<[u8]>> Ipv6Hint<Octs>

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

Parses an ‘ipv6hint’ value from its wire format.
