# `ace-can`
2+
3+
ISO-TP implementation (ISO 15765-2). Provides the reassembler and segmenter used by `ace-gateway`'s `IsoTpNode` to bridge DoIP UDS payloads to CAN frames.
4+
5+
**Design:** addressing mode (Normal / Extended / Mixed) is a caller concern. The reassembler and segmenter operate on pure PCI bytes — callers strip/prepend the address byte at the transport boundary.
6+
7+
```rust
8+
// Segmenter — owns its payload buffer, no lifetime, no unsafe
9+
let mut seg = Segmenter::<4096>::new(SegmenterConfig::classic(Normal));
10+
seg.start(&uds_payload)?;
11+
12+
let mut out = [0u8; 8];
13+
loop {
14+
match seg.next_frame(&mut out)? {
15+
SegmentResult::Frame { len } => { /* put out[..len] on CAN bus */ }
16+
SegmentResult::Complete => break,
17+
SegmentResult::WaitForFlowControl => {
18+
// wait for FC from receiver then call seg.handle_flow_control(fc)
19+
}
20+
}
21+
}
22+
```
23+
24+
```rust
25+
// Reassembler
26+
let mut rsm = Reassembler::<4096>::new(ReassemblerConfig::new(Normal));
27+
match rsm.feed(&can_frame_bytes)? {
28+
ReassembleResult::Complete { len } => { /* rsm.message(len) */ }
29+
ReassembleResult::FlowControl { .. } => { /* send FC back */ }
30+
ReassembleResult::InProgress => {}
31+
ReassembleResult::SessionAborted { .. } => {}
32+
}
33+

# `ace-client`

UDS tester client state machine (ISO 14229-1 tester side).
4+
5+
A dumb request/response pipe. Sends raw UDS frames, emits `ClientEvent`s as responses arrive. Tracks P2/P2* timeouts per pending request. Session state, security state, and retry logic are the caller's responsibility.
6+
7+
```rust
8+
let mut client = UdsClient::<1>::new(config, address);
9+
10+
// Send a request
11+
client.request(&[0x10, 0x03], now)?;
12+
13+
// After ticking, drain events
14+
for event in client.drain_events() {
15+
match event {
16+
ClientEvent::PositiveResponse { sid, data } => { /* ... */ }
17+
ClientEvent::NegativeResponse { sid, nrc } => { /* ... */ }
18+
ClientEvent::ResponsePending { sid } => { /* extended timeout active */ }
19+
ClientEvent::Timeout { sid } => { /* no response in time */ }
20+
ClientEvent::PeriodicData { did, data } => { /* periodic DID data */ }
21+
ClientEvent::Unsolicited { data } => { /* unmatched frame */ }
22+
}
23+
}
24+
```
25+
26+
Periodic DID subscriptions control classification of `0xF2xx` response frames:
27+
28+
```rust
29+
client.subscribe_periodic(0x90); // DID 0xF290 low byte
30+
client.unsubscribe_periodic(0x90);
31+
```

# `ace-core`

Foundation layer. Defines the three codec traits that everything else builds on:
4+
5+
- `FrameRead<'a>` — zero-copy decode from a `&mut &'a [u8]` cursor
6+
- `FrameWrite` — encode into a `Writer` (either `&mut [u8]` or `BytesMut`)
7+
- `Writer` — sealed trait abstracting alloc and no-alloc write targets
8+
9+
Also provides `DiagError`, `AddressMode`, `DiagnosticAddress`, and the `FrameIter<'a, T>` lazy iterator for variable-length repeated fields.

# `ace-doip`

3+
DoIP typed message and session layer implementing ISO 13400-2.
4+
5+
**Message layer** — all payload types as structs deriving `FrameCodec`: `RoutingActivationRequest`, `RoutingActivationResponse`, `DiagnosticMessage`, `DiagnosticMessageAck`, `DiagnosticMessageNack`, `VehicleAnnouncementMessage`, `EntityStatusResponse`, `AliveCheckRequest`, `AliveCheckResponse`, and more.
6+
7+
**Session layer** — `ActivationStateMachine` and `ConnectionState` model the per-TCP-connection routing activation lifecycle:
8+
9+
```
10+
Idle → ActivationPending → Active → Deactivated
11+
```
12+
13+
`ActivationAuthProvider` is a hook trait for OEM-specific authentication on `CentralSecurity` (0xFF) activation:
14+
15+
```rust
16+
pub trait ActivationAuthProvider {
17+
fn authenticate(
18+
&mut self,
19+
source_address: u16,
20+
oem_data: &[u8],
21+
) -> Result<(), ActivationDenialReason>;
22+
}
23+
```
24+
25+
`DoipFrameExt` provides semantic accessors on `DoipFrame`:
26+
27+
```rust
28+
frame.validate_header()?; // checks version, inverse, type, length
29+
frame.payload_type(); // Option<Result<PayloadType, _>>
30+
frame.payload_bytes(); // Option<&[u8]> — bytes after 8-byte header
31+
frame.payload_length_declared(); // length from header bytes 4-7
32+
```
