[][src]Struct sgx_tstd::net::Ipv4Addr

pub struct Ipv4Addr { /* fields omitted */ }

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.

The size of an Ipv4Addr struct may vary depending on the target operating system.

Textual representation

Ipv4Addr provides a FromStr implementation. The four octets are in decimal notation, divided by . (this is called "dot-decimal notation").

Methods

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.

pub const LOCALHOST: Self[src]

An IPv4 address with the address pointing to localhost: 127.0.0.1.

pub const UNSPECIFIED: Self[src]

An IPv4 address representing an unspecified address: 0.0.0.0

pub const BROADCAST: Self[src]

An IPv4 address representing the broadcast address: 255.255.255.255

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

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

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.

pub 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.

pub 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

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

This property is defined by IETF RFC 3927.

pub fn is_global(&self) -> bool[src]

Returns true if the address appears to be globally routable. See iana-ipv4-special-registry.

The following return false:

pub fn is_shared(&self) -> bool[src]

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

pub fn is_ietf_protocol_assignment(&self) -> bool[src]

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:

pub fn is_benchmarking(&self) -> bool[src]

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.

pub fn is_reserved(&self) -> bool[src]

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.

pub 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.

pub 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.

pub 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)

pub fn to_ipv6_compatible(&self) -> Ipv6Addr[src]

Converts this address to an IPv4-compatible IPv6 address.

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

pub fn to_ipv6_mapped(&self) -> Ipv6Addr[src]

Converts this address to an IPv4-mapped IPv6 address.

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