Struct SimBus 

pub struct SimBus<const MAX_DATA: usize, const MAX_QUEUED: usize> { /* private fields */ }

The simulation message bus.

Connects all nodes in the simulation. Drives time forward, delivers messages, and injects faults according to FaultConfig.

N - max message payload bytes Q - max messages in-flight simultaneously

Implementations

impl<const MAX_DATA: usize, const MAX_QUEUED: usize> SimBus<MAX_DATA, MAX_QUEUED>

pub fn new(seed: u64, faults: FaultConfig) -> Self

pub fn now(&self) -> Instant

Returns the current simulation time.

pub fn tick( &mut self, duration: Duration, ) -> Vec<Envelope<MAX_DATA>, MAX_QUEUED>

Advances simulation time by duration and returns all messages that are due for delivery at or before the new time.

pub fn send(&mut self, src: NodeAddress, dst: NodeAddress, data: &[u8]) -> bool

Enqueues a message from src to dst with fault injection applied.

Returns true if the message was enqueued, false if it was dropped by fault injection or the queue is full

pub fn faults(&self) -> &FaultConfig

Returns a reference to the current fault config

pub fn set_faults(&mut self, faults: FaultConfig)

Returns the fault config - allows escalating fault severity during a simulation run.

pub fn next_u8(&mut self) -> u8

Returns the RNG seed-derived next value - useful for injecting spontaneous NRCs at the node level.

pub fn chance(&mut self, numerator: u32, denominator: u32) -> bool

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

Formats the value using the given formatter.
