Struct Rule 

pub struct Rule { /* private fields */ }

A rule for controlling packet routing. Rules can be build with RuleBuilder and require at least one filter constraint, and an action.

Implementations

impl Rule

pub fn builder() -> RuleBuilder

Creates a RuleBuilder

pub fn action(action: Action) -> RuleBuilder

Creates a RuleBuilder and sets the rule’s Action

The action applies to all packets matching the rule, unless overridden by successive rules.

pub fn protocol(protocol: Protocol) -> RuleBuilder

Creates a RuleBuilder and sets the rule’s Protocol

pub fn source_cidr(cidr_range: impl IntoIpNet) -> RuleBuilder

Creates a RuleBuilder and sets the source CIDR.

Accepts any IP address or CIDR notation:

• "127.0.0.1": matches a single IP
• "10.0.0.0/24": matches a CIDR

This additionally accepts std::net::IpAddr, std::net::Ipv4Addr, std::net::Ipv6Addr, ipnet::IpNet, ipnet::Ipv4Net, and ipnet::Ipv6Net.

pub fn source_port(port: impl IntoPortRange) -> RuleBuilder

Creates a RuleBuilder and sets the source port

Accepts a u16 or range

pub fn destination_cidr(cidr_range: impl IntoIpNet) -> RuleBuilder

Creates a RuleBuilder and sets the destination CIDR.

Accepts any IP address or CIDR notation:

• "127.0.0.1": matches a single IP
• "10.0.0.0/24": matches a CIDR

This additionally accepts std::net::IpAddr, std::net::Ipv4Addr, std::net::Ipv6Addr, ipnet::IpNet, ipnet::Ipv4Net, and ipnet::Ipv6Net.

pub fn destination_port(port: impl IntoPortRange) -> RuleBuilder

Creates a RuleBuilder and sets the destination port

Accepts a u16 or range

Trait Implementations

impl TryFrom<RuleBuilder> for Rule

type Error = RuleError

The type returned in the event of a conversion error.

fn try_from(value: RuleBuilder) -> Result<Self, Self::Error>

Performs the conversion.
