Implementations
impl Ipv4Addr
[src]
pub const fn new(a: u8, b: u8, c: u8, d: u8) -> Ipv4Addr
[src]
Creates a new IPv4 address from four eight-bit octets.
The result will represent the IP address a
.b
.c
.d
.
Examples
use w5500_ll::net::Ipv4Addr; let addr = Ipv4Addr::new(127, 0, 0, 1);
pub const LOCALHOST: Ipv4Addr
[src]
An IPv4 address with the address pointing to localhost: 127.0.0.1.
Examples
use w5500_ll::net::Ipv4Addr; let addr = Ipv4Addr::LOCALHOST; assert_eq!(addr, Ipv4Addr::new(127, 0, 0, 1));
pub const UNSPECIFIED: Ipv4Addr
[src]
An IPv4 address representing an unspecified address: 0.0.0.0
Examples
use w5500_ll::net::Ipv4Addr; let addr = Ipv4Addr::UNSPECIFIED; assert_eq!(addr, Ipv4Addr::new(0, 0, 0, 0));
pub const BROADCAST: Ipv4Addr
[src]
An IPv4 address representing the broadcast address: 255.255.255.255
Examples
use w5500_ll::net::Ipv4Addr; let addr = Ipv4Addr::BROADCAST; assert_eq!(addr, Ipv4Addr::new(255, 255, 255, 255));
pub const fn is_unspecified(&self) -> bool
[src]
Returns true
for the special ‘unspecified’ address (0.0.0.0).
This property is defined in UNIX Network Programming, Second Edition, W. Richard Stevens, p. 891; see also ip7.
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(0, 0, 0, 0).is_unspecified(), true); assert_eq!(Ipv4Addr::new(45, 22, 13, 197).is_unspecified(), false);
pub const fn is_loopback(&self) -> bool
[src]
Returns true
if this is a loopback address (127.0.0.0/8).
This property is defined by IETF RFC 1122.
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(127, 0, 0, 1).is_loopback(), true); assert_eq!(Ipv4Addr::new(45, 22, 13, 197).is_loopback(), false);
pub const fn is_private(&self) -> bool
[src]
Returns true
if this is a private address.
The private address ranges are defined in IETF RFC 1918 and include:
- 10.0.0.0/8
- 172.16.0.0/12
- 192.168.0.0/16
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(10, 0, 0, 1).is_private(), true); assert_eq!(Ipv4Addr::new(10, 10, 10, 10).is_private(), true); assert_eq!(Ipv4Addr::new(172, 16, 10, 10).is_private(), true); assert_eq!(Ipv4Addr::new(172, 29, 45, 14).is_private(), true); assert_eq!(Ipv4Addr::new(172, 32, 0, 2).is_private(), false); assert_eq!(Ipv4Addr::new(192, 168, 0, 2).is_private(), true); assert_eq!(Ipv4Addr::new(192, 169, 0, 2).is_private(), false);
pub const fn is_link_local(&self) -> bool
[src]
Returns true
if the address is link-local (169.254.0.0/16).
This property is defined by IETF RFC 3927.
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(169, 254, 0, 0).is_link_local(), true); assert_eq!(Ipv4Addr::new(169, 254, 10, 65).is_link_local(), true); assert_eq!(Ipv4Addr::new(16, 89, 10, 65).is_link_local(), false);
pub const fn is_multicast(&self) -> bool
[src]
Returns true
if this is a multicast address (224.0.0.0/4).
Multicast addresses have a most significant octet between 224 and 239, and is defined by IETF RFC 5771.
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(224, 254, 0, 0).is_multicast(), true); assert_eq!(Ipv4Addr::new(236, 168, 10, 65).is_multicast(), true); assert_eq!(Ipv4Addr::new(172, 16, 10, 65).is_multicast(), false);
pub const fn is_broadcast(&self) -> bool
[src]
Returns true
if this is a broadcast address (255.255.255.255).
A broadcast address has all octets set to 255 as defined in IETF RFC 919.
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(255, 255, 255, 255).is_broadcast(), true); assert_eq!(Ipv4Addr::new(236, 168, 10, 65).is_broadcast(), false);
pub const fn is_documentation(&self) -> bool
[src]
Returns true
if this address is in a range designated for documentation.
This is defined in IETF RFC 5737:
- 192.0.2.0/24 (TEST-NET-1)
- 198.51.100.0/24 (TEST-NET-2)
- 203.0.113.0/24 (TEST-NET-3)
Examples
use w5500_ll::net::Ipv4Addr; assert_eq!(Ipv4Addr::new(192, 0, 2, 255).is_documentation(), true); assert_eq!(Ipv4Addr::new(198, 51, 100, 65).is_documentation(), true); assert_eq!(Ipv4Addr::new(203, 0, 113, 6).is_documentation(), true); assert_eq!(Ipv4Addr::new(193, 34, 17, 19).is_documentation(), false);
