Struct Net 

pub struct Net { /* private fields */ }

Implementations

impl Net

pub fn new() -> Self

pub fn with_config(cfg: KernelConfig) -> Self

cfg is applied to every host added later.

pub fn add_host<A: ToIpAddrs>(&mut self, addrs: A) -> HostId

Register a host. addrs accepts hostnames (auto-allocated to 192.168.x.x on first sight, idempotent on reuse) or literal IPs. Loopback (127.0.0.1, ::1) is implicit — do not pass it. Panics if an address is already claimed by another host, or if loopback is passed explicitly. The first host added becomes current.

pub fn lookup(&mut self, name: &str) -> IpAddr

Resolve name to its registered IP, allocating if unseen. Mirrors the name resolution used by Net::add_host and the shim’s hostname-aware socket addrs.

pub fn host_ids(&self) -> impl Iterator<Item = HostId> + '_

pub fn rule(&mut self, rule: impl Rule)

Install a rule for the life of the Net. Use this when the rule is part of the test’s fixed setup (symmetric latency, permanent packet filter, etc). For rules that only apply to a phase of the test, use the guard-returning rule free function from inside the sim instead.

pub fn enter(self) -> EnterGuard

Panics if another Net is already installed on this thread.

Trait Implementations

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

Formats the value using the given formatter.

impl Default for Net

fn default() -> Self

Returns the “default value” for a type.
