[−]
[src]
pub struct Ipv4Addr {
// some fields omitted
}Representation of an IPv4 address.
Methods
impl Ipv4Addr
fn new(a: u8, b: u8, c: u8, d: u8) -> Ipv4Addr
Creates a new IPv4 address from four eight-bit octets.
The result will represent the IP address a.b.c.d.
fn octets(&self) -> [u8; 4]
Returns the four eight-bit integers that make up this address.
fn is_unspecified(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true for the special 'unspecified' address 0.0.0.0.
fn is_loopback(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if this is a loopback address (127.0.0.0/8).
fn is_private(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if this is a private address.
The private address ranges are defined in RFC1918 and include:
- 10.0.0.0/8
- 172.16.0.0/12
- 192.168.0.0/16
fn is_link_local(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if the address is link-local (169.254.0.0/16).
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.
The following return false:
- private address (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16)
- the loopback address (127.0.0.0/8)
- the link-local address (169.254.0.0/16)
- the broadcast address (255.255.255.255/32)
- test addresses used for documentation (192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24)
fn is_multicast(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if this is a multicast address.
Multicast addresses have a most significant octet between 224 and 239.
fn is_broadcast(&self) -> bool
ip #27709): extra functionality has not been scrutinized to the level that it should be stable
Returns true if this is a broadcast address.
A broadcast address has all octets set to 255 as defined in RFC 919.
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.
This is defined in 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)
fn to_ipv6_compatible(&self) -> Ipv6Addr
Converts this address to an IPv4-compatible IPv6 address.
a.b.c.d becomes ::a.b.c.d
fn to_ipv6_mapped(&self) -> Ipv6Addr
Converts this address to an IPv4-mapped IPv6 address.
a.b.c.d becomes ::ffff:a.b.c.d
