Struct postgres_inet::MaskedIpAddr

pub struct MaskedIpAddr { /* fields omitted */ }

An IP address with a netmask.

Methods

impl MaskedIpAddr

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

Creates a new MaskedIpAddr from components.

Do not pass an addr with bits set to the right of the netmask if you intend to insert this into a postgres cidr field.

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);

pub fn is_unspecified(&self) -> bool

Returns true for the special 'unspecified' address.

See the documentation for Ipv4Addr::is_unspecified and Ipv6Addr::is_unspecified for more details.

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());

pub fn is_loopback(&self) -> bool

Returns true if this is a loopback address.

See the documentation for Ipv4Addr::is_loopback and Ipv6Addr::is_loopback for more details.

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());

pub fn is_multicast(&self) -> bool

Returns true if this is a multicast address.

See the documentation for Ipv4Addr::is_multicast and Ipv6Addr::is_multicast for more details.

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());

pub fn is_ipv4(&self) -> bool

Returns true if this address is an IPv4 address, and false otherwise.

Examples

assert!(MaskedIpAddr::new(Ipv4Addr::new(203, 0, 113, 6), 32).is_ipv4());
assert!(!MaskedIpAddr::new(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0), 128).is_ipv4());

pub fn is_ipv6(&self) -> bool

Returns true if this address is an IPv6 address, and false otherwise.

Examples

assert!(!MaskedIpAddr::new(Ipv4Addr::new(203, 0, 113, 6), 32).is_ipv6());
assert!(MaskedIpAddr::new(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0), 128).is_ipv6());

pub fn address(&self) -> IpAddr

Returns the contained IP address.

Examples

let ip = Ipv4Addr::new(192, 0, 2, 142);
assert_eq!(MaskedIpAddr::new(ip, 32).address(), ip);
let network = Ipv6Addr::new(0x2001, 0x0DB8, 0, 0, 0, 0, 0, 0);
assert_eq!(MaskedIpAddr::new(network, 32).address(), network);

pub fn netmask(&self) -> u8

Returns the contained netmask.

Examples

assert_eq!(MaskedIpAddr::new(Ipv4Addr::new(192, 0, 2, 142), 32).netmask(), 32);
assert_eq!(MaskedIpAddr::new(Ipv6Addr::new(0x2001, 0x0DB8, 0, 0, 0, 0, 0, 0), 64).netmask(), 64);

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

Consumes the MaskedIpAddr, returning the IP address and netmask.

Examples

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