OxiCUDA 0.4.0 is an on-device validation pass: for the first time, hand-written PTX across 60+ crates was JIT-compiled and run on real NVIDIA hardware (RTX A4000, sm_86, CUDA 12.4) instead of only checked for CPU-logic parity — catching register-shadowing bugs, base-2/base-e math errors, invalid PTX, and literal stub kernels. 38,093 tests passing, ~1.27M SLoC, 73 crates.
SciRS2 0.6.0 introduces the pure-Rust oxicuda-* CUDA stack as a direct, per-crate NVIDIA performance backend and decentralizes GPU out of scirs2-core. Ten crates — fft, symbolic, interpolate, special, stats, graph, linalg, optimize, datasets, and vision — gain an off-by-default, runtime-probed, f64-native cuda feature standing alongside the existing wgpu/WebGPU portability path, now standardized under one wgpu feature name across the ecosystem. A default build still compiles zero oxicuda. Pure Rust, Apache-2.0.
sklears 0.1.2 brings 12 real preprocessing implementations (no more stubs), SciRS2 0.5.1 upgrade, AVX2 quicksort in sklears-simd, advanced categorical imputers, and a full benchmarking regression-detection subsystem — 12,242 tests across 36 crates, >99% scikit-learn API coverage held.
ToRSh 0.1.3 lands the oxicuda GPU backend (no CUDA SDK at build time), eliminates the last C/asm dependency, ships a bandwidth-optimal ring all-reduce, completes the Node.js N-API layer, and delivers 15–30% throughput gains from phase-4 chunking helpers.
phop 0.1.0 — a pure-Rust differentiable symbolic-discovery engine that learns the topology and constants of closed-form laws by gradient descent over trees of a single operator, eml(x,y)=exp(x)−ln(y), then certifies and SMT/Lean-proves them. Runs the whole pipeline in the browser via WASM.
SciRS2 0.5.1 is a correctness and Pure-Rust hardening release: exact autograd gradients for matrix functions (Sylvester / Daleckii–Krein / reduced-SVD VJP), a restored CoreError #[non_exhaustive] contract, honest GPU/CUDA reporting, public Zarr v2/v3, and the removal of the C/MPFR rug, C rusqlite, and tokenizers dependencies. 36,606 tests, zero warnings — the sovereign scientific-computing layer of the COOLJAPAN ecosystem.
TrustformeRS 0.1.3 patch — real SHAP/LIME/Integrated-Gradients interpretability, ZeroCopyTensorView + GlobalMemoryPool + GlobalProfiler, Miri-verified memory-pool fixes, real SHA-256 on the HuggingFace upload path, and real OOXML .xlsx export via oxiarc-archive.
OxiSQL is the COOLJAPAN Pure-Rust unified SQL layer: a single async facade over embedded engines, PostgreSQL and MySQL wire clients, and a C-free SQLite-compatible path — replacing libpq, libmysqlclient, libsqlite3, and rusqlite with no FFI. Part of the NoFFI / COOLJAPAN sovereign Rust stack.
OxiHTTP is the COOLJAPAN Pure-Rust HTTP stack: an async client and server for HTTP/1.1, HTTP/2, and HTTP/3 with no curl, no OpenSSL, and no -sys crates. Transport security comes from OxiTLS. A reqwest/hyper-free facade and part of the NoFFI sovereign Rust stack.
OxiRPC is the COOLJAPAN Pure-Rust gRPC stack: tonic-style gRPC over HTTP/2 whose proto codegen, TLS, and compression are 100% Pure Rust. No protoc binary, no OpenSSL, no ring by default — codegen via OxiProto, TLS via OxiTLS, gzip/zstd via OxiARC. Part of the NoFFI sovereign Rust stack.
Meet OxiStore: the COOLJAPAN Pure Rust low-level storage layer — embedded key-value (B-tree + LSM), columnar in-memory & on-disk, and a blob abstraction (local fs + S3/Azure/GCS). Replaces librocksdb-sys, lmdb-sys, and leveldb-sys with zero FFI. Part of the NoFFI sovereign Rust stack.
OxiText is the COOLJAPAN Pure-Rust text pipeline — shaping, UAX #9 bidi reordering, UAX #14 line-breaking, layout, and glyph rasterization. A NoFFI replacement for the HarfBuzz + FriBidi + ICU + FreeType C/C++ stack, pairing with OxiFont. Part of the sovereign Rust stack.
OxiUI is the COOLJAPAN Pure Rust UI layer — no GTK (C), no Qt (C++), no SDL (C), no raw AppKit/Win32/Cocoa bindings. A thin facade over egui and iced, rendered through wgpu or a CPU rasteriser, windowed through winit, with text shaped by OxiText + OxiFont. Part of the NoFFI sovereign Rust stack.
OxiAudio is the COOLJAPAN Pure-Rust audio codec and DSP layer — decode FLAC/WAV/MP3/Vorbis/AAC/ALAC/Opus/WavPack/Musepack/MIDI and encode WAV/RF64/FLAC/AIFF/AU with no FFI, plus a full DSP toolkit (filters, dynamics, reverb, phase vocoder, pitch detection, EBU R128 loudness, MFCC/STFT). A clean, memory-safe alternative to libFLAC, libvorbis, libopus, and dr_libs — part of the NoFFI / COOLJAPAN sovereign Rust stack.
Meet OxiCrypto: the COOLJAPAN Pure Rust cryptographic primitives layer — hashes, MACs, AEADs, signatures, key exchange, KDFs, password hashing, CSPRNGs, and a post-quantum preview (ML-KEM / ML-DSA / SLH-DSA). Zero *-sys crates by default, no C toolchain, the NoFFI replacement for OpenSSL, BoringSSL, ring, and aws-lc-rs as crypto backends.
OxiFont is the COOLJAPAN Pure Rust font discovery, parsing, subsetting, and web-font layer for the oxi* ecosystem. It replaces the fontconfig + FreeType C/C++ pair with zero-FFI Rust: enumerate system fonts on Linux/macOS/Windows, parse TTF/OTF/TTC/WOFF/WOFF2, do CSS Level 4 family matching, and subset to WOFF2. Part of the NoFFI sovereign Rust stack.
OxiQUIC is the COOLJAPAN Pure Rust QUIC transport and HTTP/3 stack. It implements RFC 9000/9001/9002 directly on the rustls QUIC TLS 1.3 API, driven by a Pure Rust crypto provider over tokio UDP — with zero dependency on ring, aws-lc-rs, or any C/C++ cryptographic library. Part of the NoFFI sovereign Rust stack.
OxiSound is the COOLJAPAN Pure-Rust audio device I/O layer — cross-platform playback and capture over ALSA, CoreAudio, and WASAPI, plus MIDI, SMF, and OSC. A NoFFI replacement for cpal/PortAudio and raw ALSA/CoreAudio/WASAPI bindings, part of the sovereign Rust stack.
OxiTLS is the COOLJAPAN Pure Rust TLS transport stack — a NoFFI replacement for OpenSSL, native-tls, and the ring / aws-lc-rs C-and-assembly crypto backends. TLS 1.3 and 1.2, mTLS, ALPN, session resumption, OCSP stapling, post-quantum key exchange, and a Pure-Rust CryptoProvider by default. The transport-security foundation under OxiHTTP, OxiQUIC, and OxiRPC.
Two days after its debut, OxiProj 0.1.1 adds Python (PyO3) and WASM bindings, Tissot indicatrix and covariance/autodiff analysis, SIMD + rayon + oxicuda GPU reprojection, and geo-types/geozero/GeoParquet interop. Still a Pure-Rust PROJ replacement — no C, no FFI.
TrustformeRS 0.1.2 patch — full Kubernetes/ACI/OpenShift deploy manifests, EnhancedProfiler exports (Flamegraph/OTLP/Jaeger), scaled-dot-product attention kernel fusion, NMS + token-classification pipelines, Q2_K/Q3_K GGUF quant; the stub-only TPU backend is removed for honesty.
OxiH5 is the COOLJAPAN Pure-Rust HDF5 reader — it parses real HDF5 files written by h5py and libhdf5 from raw bytes, with no hdf5-sys, no C libhdf5, and no unsafe in production paths. All 11 datatype classes, every chunk index, deflate/shuffle/fletcher32/szip/nbit/scaleoffset filters, mmap, and a NetCDF-4 reader on top — part of the NoFFI sovereign Rust stack.
OxiNum is the COOLJAPAN Pure-Rust arbitrary-precision math layer: bignum integers, exact rationals, high-precision floats, and complex numbers — replacing GMP, MPFR, and the rug / gmp-mpfr-sys bindings with zero C and zero FFI. Part of the NoFFI sovereign Rust stack.
OxiProto is the COOLJAPAN Pure-Rust Protocol Buffers stack — a native .proto parser, codegen, and wire runtime that replaces the protoc C++ compiler. No protoc binary, no build-time C++, no -sys crates. Proto2 + proto3, multi-file imports, reflection, JSON, and a CLI, all part of the NoFFI sovereign Rust stack.
