Implementations

impl IpAddrV4

use asyncio::ip::IpAddrV4;

assert!(IpAddrV4::new(192,168,0,1).is_class_c());

pub fn is_private(&self) -> bool

Returns true for if this is a private address.

The private address ranges:

• 10.0.0.0/8
• 172.16.0.0/12
• 192.168.0.0/16

Examples

use asyncio::ip::IpAddrV4;

assert!(IpAddrV4::new(192,168,0,1).is_private());

pub fn is_multicast(&self) -> bool

Returns true for if this is a class D address.

The class D address ranges:

• 224.0.0.0/4

Examples

use asyncio::ip::IpAddrV4;

assert!(IpAddrV4::new(224,0,0,1).is_multicast());

pub fn is_link_local(&self) -> bool

Returns true for if this is a link-local address.

The link-local address ranges:

• 169.254.0.0/16

Examples

use asyncio::ip::IpAddrV4;

assert!(IpAddrV4::new(169,254,0,0).is_link_local());

pub fn as_bytes(&self) -> &[u8; 4]

Returns 4 octets bytes.

Examples

use asyncio::ip::IpAddrV4;

assert_eq!(IpAddrV4::new(169,254,0,1).as_bytes(), &[169,254,0,1]);

pub fn to_u32(&self) -> u32

Returns u32 in host byte order.

Examples

use asyncio::ip::IpAddrV4;

assert_eq!(IpAddrV4::new(10,0,0,1).to_u32(), 10*256*256*256+1);
