Struct HostFirewallGuard 

pub struct HostFirewallGuard { /* private fields */ }

RAII guard for installed host firewall rules.

Dropping the guard removes only the managed table/anchor. It does not flush the host’s main firewall ruleset.

Implementations

impl HostFirewallGuard

pub const fn platform_supported() -> bool

True when this target has an implemented host firewall backend.

pub fn platform_available() -> bool

True when this target has an implemented backend and the required platform command is present.

pub fn install(config: &HostFirewallConfig) -> Result<Self, HostFirewallError>

Install host firewall rules for the configured mesh interface.

Returns an error on unsupported platforms or when the platform firewall command is unavailable. Callers should treat that as a hard failure before exposing the host tunnel.

pub fn cleanup_disabled_artifacts(config: &HostFirewallConfig)

Remove managed firewall artifacts without requiring a live guard.

Useful after crash/restart paths where the previous process may have died before its guard could drop.

Trait Implementations

impl Debug for HostFirewallGuard

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

Formats the value using the given formatter.

impl Drop for HostFirewallGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
