Struct Ipv4Addr

#[repr(C)]
pub struct Ipv4Addr { /* private fields */ }

Representation of an IPv4 host address.

Note that this isn’t an IPv4 socket address type; use SockAddrIpv4 to represent both the host address and port number for an IPv4 socket.

Implementations

impl Ipv4Addr

pub const ANY: Self

Equivalent to the constant INADDR_ANY in C.

pub const NONE: Self

Equivalent to the constant INADDR_NONE in C.

pub const BROADCAST: Self

Equivalent to the constant INADDR_BROADCAST in C.

pub const DUMMY: Self

Equivalent to the constant INADDR_DUMMY in C.

pub const LOOPBACK: Self

Equivalent to the constant INADDR_LOOPBACK in C.

pub const UNSPEC_GROUP: Self

Equivalent to the constant INADDR_UNSPEC_GROUP in C.

pub const ALLHOSTS_GROUP: Self

Equivalent to the constant INADDR_ALLHOSTS_GROUP in C.

pub const ALLRTRS_GROUP: Self

Equivalent to the constant INADDR_ALLRTRS_GROUP in C.

pub const ALLSNOOPERS_GROUP: Self

Equivalent to the constant INADDR_ALLSNOOPERS_GROUP in C.

pub const fn from_u32(raw: u32) -> Self

Constructs an Ipv4Addr directly from a u32 value written in the host byte order.

For example, the standard loopback address 127.0.0.1 should be provided as 0x7f000001 on all platforms, which would be encoded as [0x01, 0x00, 0x00, 0x7f] on a little-endian system but this function will then convert it to network byte order automatically.

pub const fn from_octets(raw: [u8; 4]) -> Self

Constructs an Ipv4Addr from the given octets which are interpreted in network byte order, meaning that the first element corresponds with the first decimal digit in the conventional four-segment dotted decimal IP address representation.

pub const fn as_u32(&self) -> u32

Returns the raw u32 value of the address in host (not network) byte order.

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

Returns the raw octets of the address in network byte order.

pub const fn to_ipv6_mapped(&self) -> Ipv6Addr

Returns the same IP address in the “IPv6 mapped” form.

impl Ipv4Addr

Additional functions available when the std feature is active, for integrating with the standard library.

pub const fn from_std(addr: Ipv4Addr) -> Self

Available on crate feature std only.

Converts the standard library’s representation of IPv4 addresses into our representation.
