Struct UdsServer 

pub struct UdsServer<H, S>
where
    H: ServerHandler,
    S: SecurityProvider,
{ /* private fields */ }

Stateful UDS ECU server state machine.

Receives raw UDS frames via [handle], uses UdsFrameExt for protocol-level decisions (SID dispatch, suppress bit, sub-function), and decodes typed messages only where structured field access is needed.

All timing is driven by [tick] - no blocking, no hardware timers, no OS calls. Suitable for direct use as a SimNode in ace-sim.

Implementations

impl<H, S> UdsServer<H, S>

where H: ServerHandler, S: SecurityProvider,

pub fn new( config: ServerConfig, handler: H, security_provider: S, address: NodeAddress, ) -> Self

pub fn address(&self) -> &NodeAddress

pub fn session_type(&self) -> u8

pub fn security_level(&self) -> u8

pub fn handle( &mut self, src: &NodeAddress, data: &[u8], now: Instant, ) -> Result<(), ServerError<H::Error>>

Receives a raw UDS frame from src.

Wraps the bytes in a UdsFrame and uses UdsFrameExt for protocol-level decisions before dispatching to service handlers. Typed message decode via to_message() is deferred to individual handlers that need structured field access.

pub fn tick(&mut self, now: Instant) -> Result<(), ServerError<H::Error>>

Advances internal timers - S3 watchdog and periodic DID scheduling.

pub fn drain_outbox( &mut self, out: &mut Vec<(NodeAddress, Vec<u8, MAX_FRAME>), MAX_OUTBOX>, ) -> usize

Drains pending outbound frames into out.

Trait Implementations

impl<H, S> Debug for UdsServer<H, S>

where H: ServerHandler + Debug, S: SecurityProvider + Debug,

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

Formats the value using the given formatter.

impl<H, S> SimNode<MAX_FRAME, MAX_OUTBOX> for UdsServer<H, S>

where H: ServerHandler, S: SecurityProvider,

fn handle( &mut self, src: &NodeAddress, data: &[u8], now: Instant, ) -> Result<(), Self::Error>

Delivers a raw UDS frame to the server.

The SimRunner calls this after the SimBus delivers a message. Errors are returned to the runner - in simulation these are observed and recorded. In production the transport layer decides whether to reset or continue.

fn tick(&mut self, now: Instant) -> Result<(), Self::Error>

Advances internal timers.

Called by the SimRunner on every tick regardless of whether any messages were delivered. Drives the S3 watchdog and periodic DID scheduling.

fn drain_outbox( &mut self, out: &mut Vec<(NodeAddress, Vec<u8, MAX_FRAME>), MAX_OUTBOX>, ) -> usize

Drains pending outbound frames into out.

The SimRunner collects these after every handle and tick call and routes them back onto the SimBus.

type Error = ServerError<<H as ServerHandler>::Error>

fn address(&self) -> &NodeAddress

Returns this node’s address on the simulation bus.
