Struct postgres_inet::MaskedIpAddr

pub struct MaskedIpAddr { /* fields omitted */ }

An IP address with a netmask.

Methods

impl MaskedIpAddr

fn new<I: Into<IpAddr>>(addr: I, mask: u8) -> MaskedIpAddr

Creates a new MaskedIpAddr from components.

Panics

Panics if the netmask is greater than 32 for an IPv4 address, or is greater than 128 for an IPv6 address.

Examples

To represent an address:

let ip = Ipv4Addr::new(192, 0, 2, 142);
MaskedIpAddr::new(ip, 32);

To represent a network:

let network = Ipv6Addr::new(0x2001, 0x0DB8, 0, 0, 0, 0, 0, 0);
MaskedIpAddr::new(network, 32);

fn is_unspecified(&self) -> bool

Returns true for the special 'unspecified' address.

Examples

assert!(MaskedIpAddr::new(Ipv4Addr::new(0, 0, 0, 0), 32).is_unspecified());
assert!(MaskedIpAddr::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0), 128).is_unspecified());

fn is_loopback(&self) -> bool

Returns true if this is a loopback address.

Examples

assert!(MaskedIpAddr::new(Ipv4Addr::new(127, 0, 0, 1), 32).is_loopback());
assert!(MaskedIpAddr::new(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1), 128).is_loopback());

fn is_multicast(&self) -> bool

Returns true if this is a multicast address.

Examples

assert!(MaskedIpAddr::new(Ipv4Addr::new(224, 254, 0, 0), 32).is_multicast());
assert!(MaskedIpAddr::new(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0), 128).is_multicast());

fn into_inner(self) -> (IpAddr, u8)

Consumes the MaskedIpAddr, returning the IP address and netmask.

Examples

let network = Ipv4Addr::new(198, 51, 100, 0);
let (network_b, netmask) = MaskedIpAddr::new(network.clone(), 24).into_inner();
assert_eq!(network, network_b);
assert_eq!(netmask, 24);
