Compact, clone-on-write vector and string.

Fixed-size big integer implementation for Rust

More efficient alternative to `serde_json::Value` which saves memory by interning primitive values and using tagged pointers.

OxiZ is a high-performance Satisfiability Modulo Theories (SMT) solver written entirely in Rust. This project is part of an initiative to reimplement Z3 in Pure Rust. Pure Rust is a fundamental requirement - no C/C++ dependencies, no FFI bindings, just clean, safe Rust code.

Blazing fast immutable collection datatypes for Rust.

Opinionated REST API types: errors (RFC 9457), pagination, health checks, and more. No HTTP client, no business logic — just types.

IronFix is a robust and efficient Rust-based implementation of the Financial Information eXchange (FIX) protocol, designed for secure and high-performance financial messaging.

SeekStorm: vector & lexical search - in-process library & multi-tenancy server, in Rust.

Weak hash tables for Rust

A high performance python~rust library for typical JSON operations in data science and engineering.

Starshard: a high-performance, lazily sharded concurrent HashMap for Rust.

Embedded NoSQL database for Node.js — pure JavaScript SQLite alternative with MongoDB-style queries. Zero native dependencies, no node-gyp, works in Electron & CLI tools. 15,000+ npm downloads per year.
