Struct IpAddrMask 

pub struct IpAddrMask {
    pub addr: IpAddr,
    pub prefix_len: u8,
}

IP address with CIDR prefix length

Used for local and remote IP address conditions in WFP filters.

Examples

use windows_wfp::IpAddrMask;
use std::net::IpAddr;

// Match a single host
let host = IpAddrMask::new("192.168.1.1".parse().unwrap(), 32);

// Match a /24 subnet
let subnet = IpAddrMask::from_cidr("192.168.1.0/24").unwrap();

// Match an IPv6 address
let ipv6 = IpAddrMask::new("::1".parse().unwrap(), 128);

Fields

addr: IpAddr

IP address (IPv4 or IPv6)

prefix_len: u8

CIDR prefix length (0-32 for IPv4, 0-128 for IPv6)

Implementations

impl IpAddrMask

pub fn new(addr: IpAddr, prefix_len: u8) -> Self

Create a new IP address with mask

pub fn from_cidr(s: &str) -> Result<Self, String>

Parse from CIDR notation (e.g., “192.168.1.0/24” or “::1/128”)

Errors

Returns an error string if the format is invalid.

pub fn is_ipv6(&self) -> bool

Returns true if this is an IPv6 address

Trait Implementations

impl Clone for IpAddrMask

fn clone(&self) -> IpAddrMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IpAddrMask

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for IpAddrMask

fn eq(&self, other: &IpAddrMask) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
