Enum CidrSubnet

pub enum CidrSubnet {
    V4([u8; 4], [u8; 4]),
    V6([u8; 16], [u8; 16]),
}
Expand description

CIDR subnet, as per RFC 4632

You might know CIDR subnets better by their textual representation where they consist of an ip address followed by a slash and a prefix number, for example 192.168.99.0/24.

The first field in the enum is the address, the second is the mask. Both are specified in network byte order.

Variants§

§

V4([u8; 4], [u8; 4])

§

V6([u8; 16], [u8; 16])

Implementations§

§

impl CidrSubnet

pub fn from_addr_prefix(addr: IpAddr, prefix: u8) -> CidrSubnet

Obtains the CidrSubnet from an ip address as well as the specified prefix number.

// The "192.0.2.0/24" example from
// https://tools.ietf.org/html/rfc5280#page-42
let addr = IpAddr::from_str("192.0.2.0").unwrap();
let subnet = CidrSubnet::from_addr_prefix(addr, 24);
assert_eq!(subnet, CidrSubnet::V4([0xC0, 0x00, 0x02, 0x00], [0xFF, 0xFF, 0xFF, 0x00]));

pub fn from_v4_prefix(addr: [u8; 4], prefix: u8) -> CidrSubnet

Obtains the CidrSubnet from an IPv4 address in network byte order as well as the specified prefix.

pub fn from_v6_prefix(addr: [u8; 16], prefix: u8) -> CidrSubnet

Obtains the CidrSubnet from an IPv6 address in network byte order as well as the specified prefix.
