Enum Ipv6

pub enum Ipv6 {}

IPv6.

Ipv6 implements Ip for IPv6.

Note that this type has no value constructor. It is used purely at the type level. Attempting to construct it by calling Default::default will panic.

Implementations

impl Ipv6

pub const LOOPBACK_IPV6_ADDRESS: UnicastAddr<Ipv6Addr> = _

The loopback address represented as a UnicastAddr.

This is equivalent to LOOPBACK_ADDRESS, except that it is a UnicastAddr witness type.

pub const ALL_NODES_LINK_LOCAL_MULTICAST_ADDRESS: MulticastAddr<Ipv6Addr> = _

The IPv6 All Nodes multicast address in link-local scope, defined in RFC 4291 Section 2.7.1.

pub const ALL_ROUTERS_LINK_LOCAL_MULTICAST_ADDRESS: MulticastAddr<Ipv6Addr> = _

The IPv6 All Routers multicast address in link-local scope, defined in RFC 4291 Section 2.7.1.

pub const SITE_LOCAL_UNICAST_SUBNET: Subnet<Ipv6Addr> = _

The (deprecated) subnet of site-local unicast addresses, defined in RFC 3513 Section 2.5.6.

The site-local unicast subnet was deprecated in RFC 3879:

The special behavior of this prefix MUST no longer be supported in new implementations. The prefix MUST NOT be reassigned for other use except by a future IETF standards action… However, router implementations SHOULD be configured to prevent routing of this prefix by default.

pub const UNICAST_INTERFACE_IDENTIFIER_BITS: u8 = 64u8

The length, in bits, of the interface identifier portion of unicast IPv6 addresses except for addresses which start with the binary value 000.

According to RFC 4291 Section 2.5.1, “[f]or all unicast addresses, except those that start with the binary value 000, Interface IDs are required to be 64 bits.”

Note that, per RFC 4862 Section 5.5.3:

a future revision of the address architecture [RFC4291] and a future link-type-specific document, which will still be consistent with each other, could potentially allow for an interface identifier of length other than the value defined in the current documents. Thus, an implementation should not assume a particular constant. Rather, it should expect any lengths of interface identifiers.

In other words, this constant may be used to generate addresses or subnet prefix lengths, but should not be used to validate addresses or subnet prefix lengths generated by other software or other machines, as it might be valid for other software or other machines to use an interface identifier length different from this one.

pub const FLOW_LABEL_BITS: u8 = 20u8

The length, in bits, of an IPv6 flow label, defined in RFC 6437 Section 2.

Trait Implementations

impl Clone for Ipv6

fn clone(&self) -> Ipv6

Returns a copy of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

Returns the “default value” for a type.

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 Ip for Ipv6

const UNSPECIFIED_ADDRESS: Ipv6Addr = _

The unspecified IPv6 address, defined in RFC 4291 Section 2.5.2.

Per RFC 4291:

The address 0:0:0:0:0:0:0:0 is called the unspecified address. It must never be assigned to any node. It indicates the absence of an address. One example of its use is in the Source Address field of any IPv6 packets sent by an initializing host before it has learned its own address.

The unspecified address must not be used as the destination address of IPv6 packets or in IPv6 Routing headers. An IPv6 packet with a source address of unspecified must never be forwarded by an IPv6 router.

const LOOPBACK_ADDRESS: SpecifiedAddr<Ipv6Addr> = _

The loopback IPv6 address, defined in RFC 4291 Section 2.5.3.

Per RFC 4291:

The unicast address 0:0:0:0:0:0:0:1 is called the loopback address. It may be used by a node to send an IPv6 packet to itself. It must not be assigned to any physical interface. It is treated as having Link-Local scope, and may be thought of as the Link-Local unicast address of a virtual interface (typically called the “loopback interface”) to an imaginary link that goes nowhere.

The loopback address must not be used as the source address in IPv6 packets that are sent outside of a single node. An IPv6 packet with a destination address of loopback must never be sent outside of a single node and must never be forwarded by an IPv6 router. A packet received on an interface with a destination address of loopback must be dropped.

const LOOPBACK_SUBNET: Subnet<Ipv6Addr> = _

The subnet of loopback IPv6 addresses, defined in RFC 4291 Section 2.4.

Note that the IPv6 loopback subnet is a /128, meaning that it contains only one address - the LOOPBACK_ADDRESS.

const MULTICAST_SUBNET: Subnet<Ipv6Addr> = _

The subnet of multicast IPv6 addresses, defined in RFC 4291 Section 2.7.

const LINK_LOCAL_UNICAST_SUBNET: Subnet<Ipv6Addr> = _

The subnet of link-local unicast addresses, defined in RFC 4291 Section 2.4.

Note that multicast addresses can also be link-local. However, there is no single subnet of link-local multicast addresses. For more details on link-local multicast addresses, see RFC 4291 Section 2.7.

const MINIMUM_LINK_MTU: Mtu = _

The IPv6 minimum link MTU, defined in RFC 8200 Section 5.

Per RFC 8200:

IPv6 requires that every link in the Internet have an MTU of 1280 octets or greater. This is known as the IPv6 minimum link MTU. On any link that cannot convey a 1280-octet packet in one piece, link- specific fragmentation and reassembly must be provided at a layer below IPv6.

const VERSION: IpVersion = IpVersion::V6

The IP version.

const VERSION_MARKER: IpVersionMarker<Self> = _

The zero-sized-type IP version marker.

const NAME: &'static str = "IPv6"

“IPv4” or “IPv6”.

type Addr = Ipv6Addr

The address type for this IP version.

fn map_ip<In: GenericOverIp<Self, Type = In> + GenericOverIp<Ipv4> + GenericOverIp<Ipv6>, Out: GenericOverIp<Self, Type = Out> + GenericOverIp<Ipv4> + GenericOverIp<Ipv6>>( input: In, _v4: impl FnOnce(<In as GenericOverIp<Ipv4>>::Type) -> <Out as GenericOverIp<Ipv4>>::Type, v6: impl FnOnce(<In as GenericOverIp<Ipv6>>::Type) -> <Out as GenericOverIp<Ipv6>>::Type, ) -> Out

fn map_ip_out<In, Out: GenericOverIp<Self, Type = Out> + GenericOverIp<Ipv4> + GenericOverIp<Ipv6>>( input: In, v4: impl FnOnce(In) -> <Out as GenericOverIp<Ipv4>>::Type, v6: impl FnOnce(In) -> <Out as GenericOverIp<Ipv6>>::Type, ) -> Out
