Struct netsim_embed::Ipv4Range

pub struct Ipv4Range { /* fields omitted */ }

A range of IPv4 addresses with a common prefix

Implementations

impl Ipv4Range

pub fn new(addr: Ipv4Addr, bits: u8) -> Ipv4Range

Create an IPv4 range with the given base address and netmask prefix length.

Example

Create the subnet 192.168.0.0/24 with Ipv4Range::new("192.168.0.0".parse().unwrap(), 24)

pub fn global() -> Ipv4Range

Return the entire IPv4 range, eg. 0.0.0.0/0

pub fn local_subnet_10() -> Ipv4Range

Returns the local network subnet 10.0.0.0/8

pub fn local_subnet_172(block: u8) -> Ipv4Range

Returns a local network subnet 172.(16 | x).0.0/16 where x is a 4-bit number given by block

Panics

If block & 0xf0 != 0

pub fn local_subnet_192(block: u8) -> Ipv4Range

Returns the local subnet 192.168.x.0/24 where x is given by block.

pub fn random_local_subnet() -> Ipv4Range

Returns a random local network subnet from one of the ranges 10.0.0.0, 172.16.0.0 or 192.168.0.0

pub fn netmask(&self) -> Ipv4Addr

Get the netmask as an IP address

pub fn netmask_prefix_length(&self) -> u8

Get the number of netmask prefix bits

pub fn base_addr(&self) -> Ipv4Addr

Get the base address of the range, ie. the lowest IP address which is part of the range.

pub fn gateway_addr(&self) -> Ipv4Addr

Get a default IP address for the range’s gateway. This is one higher than the base address of the range. eg. for 10.0.0.0/8, the default address for the gateway will be 10.0.0.1

pub fn random_client_addr(&self) -> Ipv4Addr

Get a random IP address from the range which is not the base address or the default for the gateway address.

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

Check whether this range contains the given IP address

pub fn split(self, num: u32) -> Vec<Ipv4Range, Global>

Split a range into num sub-ranges

Panics

If the range is too small to be split up that much.
