Struct klickhouse::Ipv4

pub struct Ipv4(pub Ipv4Addr);

Wrapper type for Clickhouse IPv4 type.

Methods from Deref<Target = Ipv4Addr>

pub const LOCALHOST: Ipv4Addr

pub const UNSPECIFIED: Ipv4Addr

pub const BROADCAST: Ipv4Addr

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

Returns the four eight-bit integers that make up this address.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(127, 0, 0, 1);
assert_eq!(addr.octets(), [127, 0, 0, 1]);

pub const fn is_unspecified(&self) -> bool

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 std::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

Returns true if this is a loopback address (127.0.0.0/8).

This property is defined by IETF RFC 1122.

Examples

use std::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

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 std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(192, 169, 0, 2).is_private(), false);

pub const fn is_link_local(&self) -> bool

Returns true if the address is link-local (169.254.0.0/16).

This property is defined by IETF RFC 3927.

Examples

use std::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_global(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

The following return false:

• private addresses (see Ipv4Addr::is_private())
• the loopback address (see Ipv4Addr::is_loopback())
• the link-local address (see Ipv4Addr::is_link_local())
• the broadcast address (see Ipv4Addr::is_broadcast())
• addresses used for documentation (see Ipv4Addr::is_documentation())
• the unspecified address (see Ipv4Addr::is_unspecified()), and the whole 0.0.0.0/8 block
• addresses reserved for future protocols (see Ipv4Addr::is_ietf_protocol_assignment(), except 192.0.0.9/32 and 192.0.0.10/32 which are globally routable
• addresses reserved for future use (see Ipv4Addr::is_reserved()
• addresses reserved for networking devices benchmarking (see Ipv4Addr::is_benchmarking())

// private addresses are not global
assert_eq!(Ipv4Addr::new(10, 254, 0, 0).is_global(), false);

assert_eq!(Ipv4Addr::new(80, 9, 12, 3).is_global(), true);

pub const fn is_shared(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

Returns true if this address is part of the Shared Address Space defined in IETF RFC 6598 (100.64.0.0/10).

Examples

#![feature(ip)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(100, 64, 0, 0).is_shared(), true);
assert_eq!(Ipv4Addr::new(100, 127, 255, 255).is_shared(), true);
assert_eq!(Ipv4Addr::new(100, 128, 0, 0).is_shared(), false);

pub const fn is_ietf_protocol_assignment(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

Returns true if this address is part of 192.0.0.0/24, which is reserved to IANA for IETF protocol assignments, as documented in IETF RFC 6890.

Note that parts of this block are in use:

• 192.0.0.8/32 is the “IPv4 dummy address” (see IETF RFC 7600)
• 192.0.0.9/32 is the “Port Control Protocol Anycast” (see IETF RFC 7723)
• 192.0.0.10/32 is used for NAT traversal (see IETF RFC 8155)

Examples

#![feature(ip)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(192, 0, 0, 0).is_ietf_protocol_assignment(), true);
assert_eq!(Ipv4Addr::new(192, 0, 0, 8).is_ietf_protocol_assignment(), true);
assert_eq!(Ipv4Addr::new(192, 0, 0, 9).is_ietf_protocol_assignment(), true);
assert_eq!(Ipv4Addr::new(192, 0, 0, 255).is_ietf_protocol_assignment(), true);
assert_eq!(Ipv4Addr::new(192, 0, 1, 0).is_ietf_protocol_assignment(), false);
assert_eq!(Ipv4Addr::new(191, 255, 255, 255).is_ietf_protocol_assignment(), false);

pub const fn is_benchmarking(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

Returns true if this address part of the 198.18.0.0/15 range, which is reserved for network devices benchmarking. This range is defined in IETF RFC 2544 as 192.18.0.0 through 198.19.255.255 but errata 423 corrects it to 198.18.0.0/15.

Examples

#![feature(ip)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(198, 17, 255, 255).is_benchmarking(), false);
assert_eq!(Ipv4Addr::new(198, 18, 0, 0).is_benchmarking(), true);
assert_eq!(Ipv4Addr::new(198, 19, 255, 255).is_benchmarking(), true);
assert_eq!(Ipv4Addr::new(198, 20, 0, 0).is_benchmarking(), false);

pub const fn is_reserved(&self) -> bool

🔬 This is a nightly-only experimental API. (ip)

Returns true if this address is reserved by IANA for future use. IETF RFC 1112 defines the block of reserved addresses as 240.0.0.0/4. This range normally includes the broadcast address 255.255.255.255, but this implementation explicitly excludes it, since it is obviously not reserved for future use.

Warning

As IANA assigns new addresses, this method will be updated. This may result in non-reserved addresses being treated as reserved in code that relies on an outdated version of this method.

Examples

#![feature(ip)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(240, 0, 0, 0).is_reserved(), true);
assert_eq!(Ipv4Addr::new(255, 255, 255, 254).is_reserved(), true);

assert_eq!(Ipv4Addr::new(239, 255, 255, 255).is_reserved(), false);
// The broadcast address is not considered as reserved for future use by this implementation
assert_eq!(Ipv4Addr::new(255, 255, 255, 255).is_reserved(), false);

pub const fn is_multicast(&self) -> bool

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 std::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

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 std::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

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 std::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);

pub const fn to_ipv6_compatible(&self) -> Ipv6Addr

Converts this address to an IPv4-compatible IPv6 address.

a.b.c.d becomes ::a.b.c.d

This isn’t typically the method you want; these addresses don’t typically function on modern systems. Use to_ipv6_mapped instead.

Examples

use std::net::{Ipv4Addr, Ipv6Addr};

assert_eq!(
    Ipv4Addr::new(192, 0, 2, 255).to_ipv6_compatible(),
    Ipv6Addr::new(0, 0, 0, 0, 0, 0, 49152, 767)
);

pub const 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

Examples

use std::net::{Ipv4Addr, Ipv6Addr};

assert_eq!(Ipv4Addr::new(192, 0, 2, 255).to_ipv6_mapped(),
           Ipv6Addr::new(0, 0, 0, 0, 0, 65535, 49152, 767));
