[src]
pub enum IpAddr { V4(Ipv4Addr), V6(Ipv6Addr), }
An IP address, either an IPv4 or IPv6 address.
Examples
Constructing an IPv4 address:
use std::net::{IpAddr, Ipv4Addr}; IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1));Run
Constructing an IPv6 address:
use std::net::{IpAddr, Ipv6Addr}; IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1));Run
Variants
V4(Ipv4Addr)
Representation of an IPv4 address.
V6(Ipv6Addr)
Representation of an IPv6 address.
Methods
impl IpAddr
[src]
fn is_unspecified(&self) -> bool
1.12.0
Returns true for the special 'unspecified' address (IPv4, IPv6).
Examples
use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; assert_eq!(IpAddr::V4(Ipv4Addr::new(0, 0, 0, 0)).is_unspecified(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0)).is_unspecified(), true);Run
fn is_loopback(&self) -> bool
1.12.0
Returns true if this is a loopback address (IPv4, IPv6).
Examples
use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; assert_eq!(IpAddr::V4(Ipv4Addr::new(127, 0, 0, 1)).is_loopback(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0x1)).is_loopback(), true);Run
fn is_global(&self) -> bool
ip
#27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if the address appears to be globally routable (IPv4, IPv6).
Examples
#![feature(ip)] use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; fn main() { assert_eq!(IpAddr::V4(Ipv4Addr::new(80, 9, 12, 3)).is_global(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0, 0, 0x1c9, 0, 0, 0xafc8, 0, 0x1)).is_global(), true); }Run
fn is_multicast(&self) -> bool
1.12.0
Returns true if this is a multicast address (IPv4, IPv6).
Examples
use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; assert_eq!(IpAddr::V4(Ipv4Addr::new(224, 254, 0, 0)).is_multicast(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0)).is_multicast(), true);Run
fn is_documentation(&self) -> bool
ip
#27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if this address is in a range designated for documentation (IPv4, IPv6).
Examples
#![feature(ip)] use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; fn main() { assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_documentation(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0)) .is_documentation(), true); }Run
fn is_ipv4(&self) -> bool
ipaddr_checker
#36949)Returns true if this address is a valid IPv4 address, false if it's a valid IPv6 address.
Examples
#![feature(ipaddr_checker)] use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; fn main() { assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_ipv4(), true); assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0)).is_ipv4(), false); }Run
fn is_ipv6(&self) -> bool
ipaddr_checker
#36949)Returns true if this address is a valid IPv6 address, false if it's a valid IPv4 address.
Examples
#![feature(ipaddr_checker)] use std::net::{IpAddr, Ipv4Addr, Ipv6Addr}; fn main() { assert_eq!(IpAddr::V4(Ipv4Addr::new(203, 0, 113, 6)).is_ipv6(), false); assert_eq!(IpAddr::V6(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0)).is_ipv6(), true); }Run
