# donglora-cobs
|
|
|
|
Minimal COBS (Consistent Overhead Byte Stuffing) encoder/decoder.
|
|
|
|
- `no_std`, zero-alloc, zero dependencies at runtime
|
|
- Spec-compliant: implements Cheshire & Baker (IEEE/ACM 1999)
|
|
- Exhaustively tested: 39 tests including cross-validation against `corncobs`
|
|
|
|
## Why our own crate?
|
|
|
|
DongLoRa is an embedded firmware project. We want:
|
|
- Zero runtime dependencies (just 130 lines of code)
|
|
- Complete control over the implementation
|
|
- Spec compliance verified against both the canonical Wikipedia vectors
|
|
AND a battle-tested third-party crate (`corncobs`)
|
|
|
|
For higher-throughput use cases, consider
|
|
[corncobs](https://crates.io/crates/corncobs) which has been
|
|
benchmark-optimized for streaming applications.
|
|
|
|
## Testing
|
|
|
|
```sh
|
|
cargo test -p donglora-cobs
|
|
```
|
|
|
|
Tests include:
|
|
- 18 canonical COBS vectors (Wikipedia / IEEE/ACM spec)
|
|
- Round-trip verification for various payload sizes
|
|
- 8 interop tests cross-validating against `corncobs` (dev-dependency)
|
|
- 500 randomized round-trip payloads verified against `corncobs`
