Struct Ipv4Inet

pub struct Ipv4Inet { /* private fields */ }

Inet type representing an IPv4 host within a network

Derived ordering, i.e. first sort by address, then by network length.

Implementations

impl Ipv4Inet

pub const fn new( addr: Ipv4Addr, len: u8, ) -> Result<Self, NetworkLengthTooLongError>

Create new host within a network from address and prefix length. If the network length exceeds the address length an error is returned.

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

Create a network containing a single address as host and the network (network length = address length).

pub fn increment(&mut self) -> bool

increments host part (without changing the network part); returns true on wrap around

pub const fn next(self) -> Option<Self>

Returns next address in network or None if it was the last address in the network

pub fn decrement(&mut self) -> bool

decrements host part (without changing the network part); returns true on wrap around

pub const fn previous(self) -> Option<Self>

Returns previous address in network or None if it was the first address in the network

pub const fn overflowing_add(self, step: u128) -> (Self, bool)

Find the nth host after the current one in the current network

Returned boolean indicates whether an overflow occured.

pub const fn overflowing_sub(self, step: u128) -> (Self, bool)

Find the nth host before the current one in the current network

Returned boolean indicates whether an overflow occured.

pub const fn network(&self) -> Ipv4Cidr

network (i.e. drops the host information)

pub const fn address(&self) -> Ipv4Addr

the host

pub const fn first_address(&self) -> Ipv4Addr

first address in the network as plain address

pub const fn first(&self) -> Self

first address in the network

pub const fn last_address(&self) -> Ipv4Addr

last address in the network as plain address

pub const fn last(&self) -> Self

last address in the network

pub const fn network_length(&self) -> u8

length in bits of the shared prefix of the contained addresses

pub const fn family(&self) -> Family

IP family of the contained address (Ipv4 or Ipv6).

pub const fn is_host_address(&self) -> bool

whether network represents a single host address

pub const fn mask(&self) -> Ipv4Addr

network mask: an pseudo address which has the first network length bits set to 1 and the remaining to 0.

pub const fn contains(&self, addr: &Ipv4Addr) -> bool

check whether an address is contained in the network

impl Ipv4Inet

pub const fn overflowing_add_u32(self, step: u32) -> (Self, bool)

Find the nth host after the current one in the current network (32-bit IPv4 variant)

Returned boolean indicates whether an overflow occured.

pub const fn overflowing_sub_u32(self, step: u32) -> (Self, bool)

Find the nth host before the current one in the current network (32-bit IPv4 variant)

Returned boolean indicates whether an overflow occured.
