Implementations

impl Address

pub const UNSPECIFIED: Address = Address([0x00; 4])

An unspecified address.

pub const BROADCAST: Address = Address([0xff; 4])

The broadcast address.

pub const MULTICAST_ALL_SYSTEMS: Address = Address([224, 0, 0, 1])

All multicast-capable nodes

pub const MULTICAST_ALL_ROUTERS: Address = Address([224, 0, 0, 2])

All multicast-capable routers

pub const fn new(a0: u8, a1: u8, a2: u8, a3: u8) -> Address

Construct an IPv4 address from parts.

pub fn from_bytes(data: &[u8]) -> Address

Construct an IPv4 address from a sequence of octets, in big-endian.

Panics

The function panics if data is not four octets long.

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

Return an IPv4 address as a sequence of octets, in big-endian.

pub fn is_unicast(&self) -> bool

Query whether the address is an unicast address.

pub fn is_broadcast(&self) -> bool

Query whether the address is the broadcast address.

pub const fn is_multicast(&self) -> bool

Query whether the address is a multicast address.

pub const fn is_unspecified(&self) -> bool

Query whether the address falls into the “unspecified” range.

pub fn is_link_local(&self) -> bool

Query whether the address falls into the “link-local” range.

pub const fn is_loopback(&self) -> bool

Query whether the address falls into the “loopback” range.
