Enum Ipv4

pub enum Ipv4 {}

IPv4.

Ipv4 implements Ip for IPv4.

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 Ipv4

pub const LIMITED_BROADCAST_ADDRESS: SpecifiedAddr<Ipv4Addr>

The limited broadcast address.

The limited broadcast address is considered to be a broadcast address on all networks regardless of subnet address. This is distinct from the subnet-specific broadcast address (e.g., 192.168.255.255 on the subnet 192.168.0.0/16). It is defined in the IANA IPv4 Special-Purpose Address Registry.

pub const CLASS_A_SUBNET: Subnet<Ipv4Addr>

The Class A subnet.

The Class A subnet is defined in RFC 1812 section 2.2.5.1.

pub const CLASS_B_SUBNET: Subnet<Ipv4Addr>

The Class B subnet.

The Class B subnet is defined in RFC 1812 section 2.2.5.1.

pub const CLASS_C_SUBNET: Subnet<Ipv4Addr>

The Class C subnet.

The Class C subnet is defined in RFC 1812 section 2.2.5.1.

pub const CLASS_D_SUBNET: Subnet<Ipv4Addr>

The Class D subnet.

This subnet is also known as the multicast subnet.

The Class D subnet is defined in RFC 1812 section 2.2.5.1.

pub const CLASS_E_SUBNET: Subnet<Ipv4Addr>

The Class E subnet.

The Class E subnet is meant for experimental purposes, and should not be used on the general internet. RFC 1812 Section 5.3.7 suggests that routers SHOULD discard packets with a source address in the Class E subnet. The Class E subnet is defined in RFC 1112 Section 4.

pub const LINK_LOCAL_MULTICAST_SUBNET: Subnet<Ipv4Addr>

The subnet of link-local multicast addresses, outlined in RFC 5771 Section 4.

pub const ALL_SYSTEMS_MULTICAST_ADDRESS: MulticastAddr<Ipv4Addr>

The multicast address subscribed to by all systems on the local network, defined in the IPv4 Multicast Address Space Registry.

pub const ALL_ROUTERS_MULTICAST_ADDRESS: MulticastAddr<Ipv4Addr>

The multicast address subscribed to by all routers on the local network, defined in the IPv4 Multicast Address Space Registry.

The IPv4 Multicast subnet, defined in RFC 1112 Section 4.

const LINK_LOCAL_UNICAST_SUBNET: Subnet<Ipv4Addr>

The subnet of link-local unicast IPv4 addresses, outlined in RFC 3927 Section 2.1.

const MINIMUM_LINK_MTU: Mtu

const VERSION: IpVersion = IpVersion::V4

The IP version.

const VERSION_MARKER: IpVersionMarker<Self>

The zero-sized-type IP version marker.

const UNSPECIFIED_ADDRESS: Ipv4Addr

The unspecified address.

const NAME: &'static str = "IPv4"

“IPv4” or “IPv6”.

type Addr = Ipv4Addr

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

Apply one of the given functions to the input and return the result.

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

impl Ord for Ipv4

fn cmp(&self, other: &Ipv4) -> Ordering
