Struct SubnetFilter 

pub struct SubnetFilter {
    pub ipv4_subnets: Vec<Ipv4Network>,
    pub ipv6_subnets: Vec<Ipv6Network>,
    pub check_source: bool,
    pub check_destination: bool,
}

Subnet filter configuration (CIDR notation)

Filters packets based on subnet membership using CIDR notation. Supports both IPv4 and IPv6 subnets.

Examples

use huginn_net_http::SubnetFilter;

// Allow only private networks
let filter = SubnetFilter::new()
    .allow("192.168.0.0/16").unwrap()
    .allow("10.0.0.0/8").unwrap();

// IPv6 subnet
let filter = SubnetFilter::new()
    .allow("2001:db8::/32").unwrap();

Fields

ipv4_subnets: Vec<Ipv4Network>

IPv4 subnets to match

ipv6_subnets: Vec<Ipv6Network>

IPv6 subnets to match

check_source: bool

Check source, destination, or both?

check_destination: bool

Implementations

impl SubnetFilter

pub fn new() -> Self

Create a new subnet filter that checks both source and destination by default

pub fn allow(self, cidr: &str) -> Result<Self, String>

Add a subnet in CIDR notation

Errors

Returns an error if the CIDR notation is invalid

Examples

use huginn_net_http::SubnetFilter;

let filter = SubnetFilter::new()
    .allow("192.168.1.0/24").unwrap();

pub fn allow_list(self, cidrs: Vec<&str>) -> Result<Self, String>

Add multiple subnets

Errors

Returns an error if any CIDR notation is invalid

Examples

use huginn_net_http::SubnetFilter;

let filter = SubnetFilter::new()
    .allow_list(vec!["192.168.0.0/16", "10.0.0.0/8", "172.16.0.0/12"])
    .unwrap();

pub fn source_only(self) -> Self

Only check source addresses

By default, both source and destination are checked.

pub fn destination_only(self) -> Self

Only check destination addresses

By default, both source and destination are checked.

pub fn matches(&self, src_ip: &IpAddr, dst_ip: &IpAddr) -> bool

Check if packet matches subnet filter

Returns

true if either source or destination IP is in any of the subnets (if enabled)

Trait Implementations

impl Clone for SubnetFilter

fn clone(&self) -> SubnetFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubnetFilter

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

Formats the value using the given formatter.

impl Default for SubnetFilter

fn default() -> SubnetFilter

Returns the “default value” for a type.
