|
|
|
|
## [2.3.0] - 2026-03-11 — Pipeline v4
|
|
|
|
### Added
|
|
- **`ChecksumCodec`** — CRC32 integrity: append on encode, verify+strip on decode, Error on mismatch
|
|
- **`RateLimitCodec`** — Token bucket algorithm (burst-tolerant, refills over time)
|
|
- **`TagCodec`** — Attach channel ID for mux routing, drop wrong-channel frames on decode
|
|
- **`Pipeline::chain()`** — Compose two pipelines into one
|
|
- **`Pipeline::describe()`** — Human-readable dump (`dedup → compress → encrypt`)
|
|
- Error propagation tested — corrupt checksum → `PipelineResult.errors`
|
|
- 474 total tests (+13 new)
|
|
|
|
## [2.2.0] - 2026-03-11 — Pipeline v3
|
|
|
|
### Added
|
|
- **`PipelineResult`** — returns frames + collected errors + consumed count
|
|
- **`StageMetric`** — per-stage frames_in/frames_out/consumed/errors observability
|
|
- **`ReassemblyCodec`** — reassemble chunked frames (counterpart to SlicerCodec)
|
|
- **`ConditionalCodec`** — wrap any codec with runtime enable/disable toggle
|
|
- **`Pipeline::signal(key)`** — preset: dedup→compress→encrypt
|
|
- **`Pipeline::media(mtu)`** — preset: compress→slicer
|
|
- **`Pipeline::metrics()`** — per-stage counter snapshot
|
|
- Slicer↔Reassembly roundtrip verified
|
|
- 461 total tests (+12 new)
|
|
|
|
## [2.1.0] - 2026-03-11 — Pipeline v2
|
|
|
|
### Added
|
|
- **`CodecOutput::Many`** — codecs can fan-out (1 frame → N frames)
|
|
- **`EncryptCodec`** — XOR cipher encrypt/decrypt adapter
|
|
- **`FilterCodec`** — drop frames by type (`FilterCodec::drop_control()`)
|
|
- **`Codec::reset()`** — clear internal state on reconnect
|
|
- **`Pipeline::encode_all/decode_all`** — batch frame processing
|
|
- **`SlicerCodec`** rewritten — real MTU chunking via `Many`
|
|
- Full roundtrip test — Compress→Encrypt→encode→decode→verify
|
|
- 449 total tests (+11 new)
