Struct Rule

Source 
pub struct Rule<I: IpExt, DeviceClass, RuleInfo> {
    pub matcher: PacketMatcher<I, DeviceClass>,
    pub action: Action<I, DeviceClass, RuleInfo>,
    pub validation_info: RuleInfo,
}
Expand description

A set of criteria (matchers) and a resultant action to take if a given packet matches.

Fields§

§matcher: PacketMatcher<I, DeviceClass>

The criteria that a packet must match for the action to be executed.

§action: Action<I, DeviceClass, RuleInfo>

The action to take on a matching packet.

§validation_info: RuleInfo

Opaque information about this rule for use when validating and converting state provided by Bindings into Core filtering state. This is only used when installing filtering state, and allows Core to report to Bindings which rule caused a particular error. It is zero-sized for validated state.
