Codec families
Selectors, interpreters and coders with enough machinery for a specification of their own.
| Specification | Scope |
|---|---|
| Entropy coders | OpenZL’s FSE/Huffman fork, PivCo-Huffman, the five entropy nodes and the entropy graph’s plan. |
| LZ codecs and graphs | lz4 (fast, HC, optimal), lz, field_lz, mux_lengths, quantize, the shared lz_common infrastructure and the LZ graphs. |
| Transformer | The numeric selector: features, generated scorers, guards, depth limits, static fallbacks, float determinism and the no_std caveat. |
| ML selector and clustering | Gradient-boosted-tree selection and tag-based clustering with their CBOR configurations. |
| SDDL and SDDL2 | The description interpreter, the bytecode VM, chunking and replay. |
| Custom codecs | Application codec registration, typed and variable ports, callback contexts, custom wire IDs, validation, errors and lifetime. |
| Dictionaries | Dict, DictBundle and BundleStore, wire formats, the encoder and decoder flows. |
