SSE HTTP-body codec decoding server-sent events into event streams and encoding SSE events into HTTP bodies; faithful line-by-line transliteration of upstream Rust implementation.

Faithful line-by-line transliteration of a UUID implementation enabling generation, parsing, formatting, version handling, and per-file provenance headers for traceability, aiming feature parity with upstream.

Line-by-line transliteration port of a mature Encoding Standard implementation. Streams and buffers convert between legacy encodings, UTF-8 and UTF-16, with mem utilities, label resolution and optional SIMD acceleration.

Geospatial toolset: GeoJSON DSL with builders and JSON serialization, ported Turf.js spatial-analysis functions, plus unit-of-measure types and formatting utilities for distances.

Generate JSON Schema documents from data types, honoring serialization attributes, offering derive-style macros, schema-from-value generation, serde-compatible behavior, and Draft 2020-12–compliant output.

Easy-to-use seccomp-bpf jailing library; define filters via JSON or code, compile to BPF, and install runtime or build-time with rule-based conditions and actions.

Efficient, generic serialization/deserialization framework with derive-style codegen, pluggable data-format adapters, and faithful line-by-line transliteration including per-file provenance headers, ensuring API parity with upstream implementation.

Line-by-line transliteration of a battle-tested base64 implementation offering high-performance encoders/decoders, engine-level APIs, canonical-padding handling, and configurable decoding for non-canonical inputs.

Build typed property views over raw object maps, decode on-demand, edit known fields, and re-emit preserving unknown fields. Supports JSON/YAML delegates, slices and null-write modes.

Derives OpenAI function-tool schemas from serialization descriptors, turning sealed request hierarchies into SDK tool declarations and decoding model function calls into typed request objects.

Maps structured serialization models to deterministic SCREAMING_SNAKE_CASE environment variables and back into typed configs, supporting nested objects, indexed lists, encode-defaults control, and testable map-based API.

Deterministic pseudo-random generators with mutable Random implementations and serializable immutable-state snapshots for reproducible simulation, testing, procedural generation; includes Philox, Threefry, xoshiro and L64X128 with block APIs.

Serialises data structures with robust reference and cyclic-graph handling, JSON-friendly output, pluggable strategies for object identity, and straightforward integration into serialization pipelines.

BER‑TLV/TLV parser for EMV payment data: recursive decode of constructed/primitive tags, hex-string I/O, comprehensive EMV tag dictionary, and rich value explainers and visualizations.

Lightweight typed ID generation and parsing with compact formats, validation, deterministic creation, and easy serialization for strongly-typed identifiers across application domains.

Complete migration of a widely-used v3.2.3 double-entry accounting system: parses and processes all ledger files, full query engine, 18 built-in plugins, CLI suite, up to 2.2× faster.

Represents tri-state fields—absent, explicitly null, or present with value—ideal for PATCH/partial updates; serializes to natural JSON shape and supplies helpers to apply and inspect patches.

Tiny decimal arithmetic API for precise monetary and exchange-rate values avoiding binary floating point; supports parsing, formatted I/O, 38-digit decimal context, rounding, base-unit conversions, serialization.

Circuit-based, zero-allocation frontend skeleton enabling deterministic, nanosecond-tier, lock-free data pipelines via flat, preallocated arrays, compiler-enforced memory budgets, SoA ECS and native UI bindings.

Typed JSON-RPC client for codex app-server: coroutine-driven session with response correlation and notification flows, high-level typed APIs, stdio/websocket transports, schema generation and testing tooling.
