Struct iprange::Subnet

pub struct Subnet {
    pub prefix: CompactIpv4,
    pub prefix_size: usize,
}

Represents a subdivision of an IP network.

We use CIDR notation to repesent a subnetwork. Thus, a Subnet is composed with a prefix and the size of the subnet written after a slash (/). The size of the subnet is represented by prefix_size, which is the count of leading ones in the subnet mask.

Subnet implements FromStr so that users can easily convert a string slice to a Subnet. Currently, two formats are supported:

• a.b.c.d/prefix_size (e.g. 10.0.0.0/8)
• a.b.c.d/mask (e.g. 192.168.0.0/255.255.255.0)

The subnet will be automatically fixed after parsing. For example: parsing 172.16.32.1/16 results in 172.16.0.0/16.

Fields

prefix: CompactIpv4

The prefix IP of the subnet

prefix_size: usize

The count of leading ones of the subnet mask

Methods

impl Subnet

fn contains<T: Into<CompactIpv4>>(&self, addr: T) -> bool

Tests if self contains the IP addr.

fn end(&self) -> CompactIpv4

Returns the last IP in self.

fn includes(&self, other: Subnet) -> bool

Tests if self includes other, in other words, self is a supernetwork of other.

fn mask(&self) -> CompactIpv4

Returns the subnet mask of self.

Trait Implementations

impl PartialEq for Subnet

fn eq(&self, __arg_0: &Subnet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Subnet) -> bool

This method tests for !=.

impl Eq for Subnet

impl Clone for Subnet

fn clone(&self) -> Subnet

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Subnet

impl From<CompactIpv4> for Subnet

fn from(ip: CompactIpv4) -> Subnet
