Struct Ipv4Addr

pub struct Ipv4Addr {
    octets: [u8; 4],
}

An IPv4 address.

IPv4 addresses are defined as 32-bit integers in IETF RFC 791. They are usually represented as four octets.

See IpAddr for a type encompassing both IPv4 and IPv6 addresses.

Textual representation

Ipv4Addr provides a FromStr implementation. The four octets are in decimal notation, divided by . (this is called “dot-decimal notation”). Notably, octal numbers (which are indicated with a leading 0) and hexadecimal numbers (which are indicated with a leading 0x) are not allowed per IETF RFC 6943.

Examples

use std::net::Ipv4Addr;

let localhost = Ipv4Addr::new(127, 0, 0, 1);
assert_eq!("127.0.0.1".parse(), Ok(localhost));
assert_eq!(localhost.is_loopback(), true);
assert!("012.004.002.000".parse::<Ipv4Addr>().is_err()); // all octets are in octal
assert!("0000000.0.0.0".parse::<Ipv4Addr>().is_err()); // first octet is a zero in octal
assert!("0xcb.0x0.0x71.0x00".parse::<Ipv4Addr>().is_err()); // all octets are in hex

Fields

octets: [u8; 4]

Implementations

impl Ipv4Addr

pub const BITS: u32 = 32u32

The size of an IPv4 address in bits.

Examples

use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::BITS, 32);

pub const LOCALHOST: Ipv4Addr

An IPv4 address with the address pointing to localhost: 127.0.0.1

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::LOCALHOST;
assert_eq!(addr, Ipv4Addr::new(127, 0, 0, 1));

pub const UNSPECIFIED: Ipv4Addr

An IPv4 address representing an unspecified address: 0.0.0.0

This corresponds to the constant INADDR_ANY in other languages.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::UNSPECIFIED;
assert_eq!(addr, Ipv4Addr::new(0, 0, 0, 0));

pub const BROADCAST: Ipv4Addr

An IPv4 address representing the broadcast address: 255.255.255.255.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::BROADCAST;
assert_eq!(addr, Ipv4Addr::new(255, 255, 255, 255));

pub const 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.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(127, 0, 0, 1);

pub const fn to_bits(self) -> u32

Converts an IPv4 address into a u32 representation using native byte order.

Although IPv4 addresses are big-endian, the u32 value will use the target platform’s native byte order. That is, the u32 value is an integer representation of the IPv4 address and not an integer interpretation of the IPv4 address’s big-endian bitstring. This means that the u32 value masked with 0xffffff00 will set the last octet in the address to 0, regardless of the target platform’s endianness.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(0x12, 0x34, 0x56, 0x78);
assert_eq!(0x12345678, addr.to_bits());

use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(0x12, 0x34, 0x56, 0x78);
let addr_bits = addr.to_bits() & 0xffffff00;
assert_eq!(Ipv4Addr::new(0x12, 0x34, 0x56, 0x00), Ipv4Addr::from_bits(addr_bits));

pub const fn from_bits(bits: u32) -> Ipv4Addr

Converts a native byte order u32 into an IPv4 address.

See Ipv4Addr::to_bits for an explanation on endianness.

Examples

use std::net::Ipv4Addr;

let addr = Ipv4Addr::from_bits(0x12345678);
assert_eq!(Ipv4Addr::new(0x12, 0x34, 0x56, 0x78), addr);

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]);

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

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

Examples

#![feature(ip_as_octets)]

use std::net::Ipv4Addr;

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

Returns true if the address appears to be globally reachable as specified by the IANA IPv4 Special-Purpose Address Registry.

Whether or not an address is practically reachable will depend on your network configuration. Most IPv4 addresses are globally reachable, unless they are specifically defined as not globally reachable.

Non-exhaustive list of notable addresses that are not globally reachable:

• The unspecified address (is_unspecified)
• Addresses reserved for private use (is_private)
• Addresses in the shared address space (is_shared)
• Loopback addresses (is_loopback)
• Link-local addresses (is_link_local)
• Addresses reserved for documentation (is_documentation)
• Addresses reserved for benchmarking (is_benchmarking)
• Reserved addresses (is_reserved)
• The broadcast address (is_broadcast)

For the complete overview of which addresses are globally reachable, see the table at the IANA IPv4 Special-Purpose Address Registry.

Examples

#![feature(ip)]

use std::net::Ipv4Addr;

// Most IPv4 addresses are globally reachable:
assert_eq!(Ipv4Addr::new(80, 9, 12, 3).is_global(), true);

// However some addresses have been assigned a special meaning
// that makes them not globally reachable. Some examples are:

// The unspecified address (`0.0.0.0`)
assert_eq!(Ipv4Addr::UNSPECIFIED.is_global(), false);

// Addresses reserved for private use (`10.0.0.0/8`, `172.16.0.0/12`, 192.168.0.0/16)
assert_eq!(Ipv4Addr::new(10, 254, 0, 0).is_global(), false);
assert_eq!(Ipv4Addr::new(192, 168, 10, 65).is_global(), false);
assert_eq!(Ipv4Addr::new(172, 16, 10, 65).is_global(), false);

// Addresses in the shared address space (`100.64.0.0/10`)
assert_eq!(Ipv4Addr::new(100, 100, 0, 0).is_global(), false);

// The loopback addresses (`127.0.0.0/8`)
assert_eq!(Ipv4Addr::LOCALHOST.is_global(), false);

// Link-local addresses (`169.254.0.0/16`)
assert_eq!(Ipv4Addr::new(169, 254, 45, 1).is_global(), false);

// Addresses reserved for documentation (`192.0.2.0/24`, `198.51.100.0/24`, `203.0.113.0/24`)
assert_eq!(Ipv4Addr::new(192, 0, 2, 255).is_global(), false);

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_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

Note that IPv4-compatible addresses have been officially deprecated. If you don’t explicitly need an IPv4-compatible address for legacy reasons, consider using 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, 0xc000, 0x2ff)
);

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, 0xffff, 0xc000, 0x2ff));

impl Ipv4Addr

pub fn parse_ascii(b: &[u8]) -> Result<Ipv4Addr, AddrParseError>

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

Parse an IPv4 address from a slice of bytes.

#![feature(addr_parse_ascii)]

use std::net::Ipv4Addr;

let localhost = Ipv4Addr::new(127, 0, 0, 1);

Trait Implementations

impl<'a> AddAnyAttr for Ipv4Addr

type Output<SomeNewAttr: Attribute> = Ipv4Addr

The new type once the attribute has been added.

fn add_any_attr<NewAttr>( self, _attr: NewAttr, ) -> <Ipv4Addr as AddAnyAttr>::Output<NewAttr>

where NewAttr: Attribute,

Adds an attribute to the view.

impl Archive for Ipv4Addr

type Archived = ArchivedIpv4Addr

The archived representation of this type.

type Resolver = ()

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, _: usize, _: <Ipv4Addr as Archive>::Resolver, out: *mut <Ipv4Addr as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl AttributeValue for Ipv4Addr

type AsyncOutput = Ipv4Addr

The type once all async data have loaded.

type State = (Element, Ipv4Addr)

The state that should be retained between building and rebuilding.

type Cloneable = Ipv4Addr

A version of the value that can be cloned. This can be the same type, or a reference-counted type. Generally speaking, this does not need to refer to the same data, but should behave in the same way. So for example, making an event handler cloneable should probably make it reference-counted (so that a FnMut() continues mutating the same closure), but making a String cloneable does not necessarily need to make it an Arc<str>, as two different clones of a String will still have the same value.

type CloneableOwned = Ipv4Addr

A cloneable type that is also 'static. This is used for spreading across types when the spreadable attribute needs to be owned. In some cases (&'a str to Arc<str>, etc.) the owned cloneable type has worse performance than the cloneable type, so they are separate.

fn html_len(&self) -> usize

An approximation of the actual length of this attribute in HTML.

fn to_html(self, key: &str, buf: &mut String)

Renders the attribute value to HTML.

fn to_template(_key: &str, _buf: &mut String)

fn hydrate<const FROM_SERVER: bool>( self, key: &str, el: &Element, ) -> <Ipv4Addr as AttributeValue>::State

Adds interactivity as necessary, given DOM nodes that were created from HTML that has either been rendered on the server, or cloned for a <template>.

fn build(self, el: &Element, key: &str) -> <Ipv4Addr as AttributeValue>::State

Adds this attribute to the element during client-side rendering.

fn rebuild(self, key: &str, state: &mut <Ipv4Addr as AttributeValue>::State)

Applies a new value for the attribute.

fn into_cloneable(self) -> <Ipv4Addr as AttributeValue>::Cloneable

Converts this attribute into an equivalent that can be cloned.

fn into_cloneable_owned(self) -> <Ipv4Addr as AttributeValue>::CloneableOwned

Converts this attributes into an equivalent that can be cloned and is 'static.

fn dry_resolve(&mut self)

“Runs” the attribute without other side effects. For primitive types, this is a no-op. For reactive types, this can be used to gather data about reactivity or about asynchronous data that needs to be loaded.

async fn resolve(self) -> <Ipv4Addr as AttributeValue>::AsyncOutput

“Resolves” this into a form that is not waiting for any asynchronous data.
