Struct CanSimBus 

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

A CAN-aware simulation bus.

Wraps SimBus for message delivery and adds CAN bus state and CAN-specific fault injection. Connection-less - any node may send to any other node as long as the bus is operational.

N - max frame payload bytes (8 for classic CAN, 64 for CAN FD) Q - max frames in-flight simultaneously

Implementations

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

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

Creates a new CanSimBus.

seed - seeds both the message bus RNG and the CAN fault RNG. The CAN RNG uses seed.wrapping_add(2) for independence.

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

Enqueues a CAN frame - rejected if the bus is in bus-off state or CAN-level fault injection drops it.

Returns true if the frame was accepted.

pub fn trigger_bus_off(&mut self)

Manually triggers bus-off - useful for DST fault injection.

pub fn reset_bus_off(&mut self)

Resets the bus from bus-off state back to Active.

pub fn bus_state(&self) -> &CanBusState

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

Advances simulation time, delivers due frames, and checks bus-off fault injection.

pub fn now(&self) -> Instant

pub fn drain_events(&mut self) -> impl Iterator<Item = CanEvent> + '_

Drains accumulated CAN events.

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

pub fn inner_mut(&mut self) -> &mut SimBus<MAX_DATA, MAX_QUEUED>

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

Formats the value using the given formatter.
