Struct NetworkPolicy 

pub struct NetworkPolicy {
    pub default_action: Action,
    pub rules: Vec<Rule>,
}

Network policy with ordered rules.

Rules are evaluated in first-match-wins order. If no rule matches, the default action is applied.

Fields

default_action: Action

Default action for traffic not matching any rule.

rules: Vec<Rule>

Ordered list of rules (first match wins).

Implementations

impl NetworkPolicy

pub fn none() -> Self

No network access — deny everything.

pub fn allow_all() -> Self

Unrestricted network access — allow everything.

pub fn public_only() -> Self

Public internet only — deny loopback, private, link-local, and cloud metadata addresses.

pub fn non_local() -> Self

Non-local network access — allow public internet and private/LAN addresses, but deny loopback, link-local, and cloud metadata addresses.

pub fn evaluate_egress(&self, dst: SocketAddr, protocol: Protocol) -> Action

Evaluate an outbound connection against the policy.

Returns the action from the first matching rule, or the default action if no rule matches.

pub fn evaluate_egress_ip(&self, dst: IpAddr, protocol: Protocol) -> Action

Evaluate an outbound ICMP packet against the policy.

Same first-match-wins logic as Self::evaluate_egress but without port matching — ICMP has no ports. Rules with a ports filter are skipped since applying a port range to a portless protocol would be semantically incorrect.
