Struct EnterGuard 

pub struct EnterGuard { /* private fields */ }

Implementations

impl EnterGuard

pub fn egress_all(&self, out: &mut Vec<Packet>)

Drain every host’s outbound queue into out. The caller decides what happens next — typically: consult rules via EnterGuard::evaluate for each packet and then EnterGuard::deliver (or schedule for later). The buffer is passed in so the caller can reuse its allocation across ticks. See fixture for the default tokio-driven loop.

pub fn deliver(&self, pkt: Packet)

Route a packet to the host owning its destination IP. Drops silently if no host is registered for that IP.

pub fn evaluate(&self, pkt: &Packet) -> Verdict

Walk installed rules for pkt. First non-Pass verdict wins; empty rule chain returns Verdict::Pass.

pub fn set_current(&self, id: HostId)

Pin which host subsequent sys() calls (i.e. socket syscalls from any task spawned inside this guard) talk to.

pub fn rule(&self, r: impl Rule) -> RuleGuard

Install a rule, vending a RuleGuard that uninstalls it on drop. Useful in schedulers or fixture code that owns the guard’s lifetime explicitly — async tasks should call the free rule function instead.

Trait Implementations

impl Drop for EnterGuard

fn drop(&mut self)
