Enum Ipv4AddressClass

pub enum Ipv4AddressClass {
    A,
    B,
    C,
    D,
    E,
}

The class of an IPv4 address.

The classful addressing scheme is obsoloted in favour of CIDR but is still used on some systems. For more information, see RFC 791 section 2.3 and RFC 1812 section 2.2.5.1.

Variants

A

A Class A IPv4 address.

B

A Class B IPv4 address.

C

A Class C IPv4 address.

D

A Class D IPv4 address.

Class D addresses are also known as multicast.

E

A Class E IPv4 address.

Class E addresses are also known as experimental.

Implementations

impl Ipv4AddressClass

pub const fn default_prefix_len(self) -> Option<u8>

Returns the default prefix length for an IPv4 address class if the prefix is well-defined.

Trait Implementations

impl Clone for Ipv4AddressClass

fn clone(&self) -> Ipv4AddressClass

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ipv4AddressClass

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Ipv4AddressClass

fn eq(&self, other: &Ipv4AddressClass) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
