OxiH5 is the COOLJAPAN Pure-Rust HDF5 reader. It parses real HDF5 files (written by h5py / libhdf5) from scratch using only std byte parsing — no *-sys, no C libhdf5, no unsafe code.

OxiHTTP is the COOLJAPAN Pure-Rust HTTP stack — a reqwest/hyper facade for the COOLJAPAN ecosystem. It provides HTTP/1.1, HTTP/2, and (in M5) HTTP/3 support without any C/C++/Fortran dependencies i…

Pure-by-default Rust gRPC stack — client and server — that requires NO protoc binary at build time, NO openssl at link time, and NO ring in its default cryptographic closure. OxiRPC does not rewrit…

OxiSound is the COOLJAPAN Pure-Rust audio device I/O layer.

OxiStore is the COOLJAPAN-blessed Pure Rust low-level storage layer: embedded key-value, columnar in-memory & on-disk, and blob storage abstraction (local fs + cloud). It exists so the dozens of Ox…

OxiCrypto is the COOLJAPAN-blessed Pure Rust cryptographic primitives layer: hashes, MACs, AEADs, signatures, key exchange, KDFs, password hashing, PRNGs, and a post-quantum preview. It is the foun…

OxiNum is Pure-Rust arbitrary-precision math — the COOLJAPAN GMP/MPFR-free replacement. OxiNum replaces rug / GMP / MPFR with a 100 % Pure Rust, MIT OR Apache-2.0 licensed implementation built on t…

OxiFont is the COOLJAPAN Pure Rust font discovery + font parsing layer for the oxi* ecosystem. It replaces the fontconfig (C, family matching + system enumeration) and freetype (C, font file parsin…

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 the oxiquic-crypto Pure-Rust crypto provider …

OxiText is the COOLJAPAN Pure-Rust text pipeline: shape → bidi → line-break → layout → rasterize. It replaces the canonical C stack — harfbuzz (shaper), pango/icu (layout + bidi + segmentation), fr…

OxiTLS is the COOLJAPAN-blessed Pure Rust TLS transport stack. It exists so a downstream cargo build --no-default-features on rust:slim produces a working TLS 1.2 / 1.3 client and server with a Pur…

OxiUI is the COOLJAPAN-blessed Pure Rust UI layer: no GTK (C), no Qt (C++), no SDL (C), no system widgets, no raw AppKit / Win32 / Cocoa bindings. It is a thin, opinionated facade over egui (immedi…

OxiProto is the COOLJAPAN Pure-Rust Protocol Buffers stack. It eliminates the build-time protoc (C++) binary that prost-build and tonic-build demand on PATH, by routing all .proto parsing and descr…

CLI proxy that reduces LLM token consumption by 60-90% on common dev commands. Single Rust binary, zero dependencies

OxiEML - A Pure Rust crate that implements the EML operator eml(x, y) = exp(x) - ln(y) and builds uniform binary trees expressing all elementary functions using only this operator and the constant 1.

Pure Rust LLM Inference Engine — The Sovereign Alternative to llama.cpp License Rust Complete GGUF model loading, multi-format quantized inference, and an OpenAI-compatible API server — all without…

OxiCUDA replaces the entire NVIDIA CUDA Toolkit software stack with type-safe, memory-safe Rust code.

OxiBonsai is a zero-FFI, zero-C/C++ inference engine for PrismML's sub-2-bit Bonsai family — both the 1-bit line (Q1_0_g128) and the ternary line (TQ2_0_g128). It runs on CPU (SIMD), Apple Silicon …

Unified physics engine written in Rust, aiming to replace Bullet, OpenFOAM, LAMMPS, and CalculiX.

An agent-managed museum exhibit, built in Rust with Gajae-Code / LazyCodex — developed and maintained with no human intervention.

OxiRouter is Autonomous Semantic Federation Engine for the Edge — Learned source selection for SPARQL federated queries with context-awareness.¥
