Link-time initialization, destruction, scattered data collection macros for Rust

Rust port of Google's SwissTable hash map

A high-performance, asynchronous toolkit for building MCP servers and clients in Rust.

Near-lock-free structured logging for Rust: a 65,536-slot ring buffer, formatting deferred to a background thread, 14 output formats (JSON, ECS, GELF, OTLP, logfmt…) and native os_log/journald sinks. Plus an OTLP/HTTP exporter, an MCP server for AI agents, Tower middleware, PII redaction, WebAssembly bindings and a jq-style CLI.

Python supercharged for the fastai library

PurRDF — one RDF 1.2 engine, one behavior, in Rust, Python, WebAssembly and C. Deterministic BM25 full-text search, exact GeoSPARQL 1.1 and embedding kNN answered from SPARQL, in-process, over one dataset: the three jobs a triple store usually kept PostgreSQL beside it for. Plus native codecs, RDFC-1.0, SHACL, ShEx, entailment and GTS transport.

A pure-Rust openEHR Clinical Data Repository: ITS-REST 1.1.0, AQL 1.1, PostgreSQL 18-native storage.

A collection of network related libraries that includes protocol parsers and daemons

Cryptography-oriented big integer library with constant-time, stack-allocated (no_std-friendly) implementations of modern formulas

Canonical type definitions for EIP-155 chains

Boolean-valued predicate functions in Rust

Managing transit data with Rust

High Performance Low-Latency Frameworks

PNA (Portable Network Archive) is a highly scalable archive format that can be compressed, encrypted, and split. Also, its data structure is inspired by the PNG data structure.

Grafeo is a pure-Rust, high-performance graph database that can be embedded as a library or run as a standalone database, with optional in-memory or persistent storage. Grafeo supports both LPG and RDF and all major query languages.

A better compressed bitset in Rust

Convert all CAD formats

The explainable, local-first memory engine for AI agents. One ~9 MB binary fuses vector + graph + columnar under VelesQL; why() returns the evidence path behind every recall. No cloud, no glue code — runs on server, browser, mobile and desktop.

🐎 A fast implementation of the Aho-Corasick algorithm using the compact double-array data structure in Rust.

Rust canister development kit for the Internet Computer.

Power system compiler infrastructure

🗻 Log-structured, embeddable key-value storage engine written in Rust

Rust cache structures and easy function memoization

Maps where keys are borrowed from values.

Connect threads, processes, hosts, and languages without a broker.

This library provides implementations of many algorithms and data structures that are useful for bioinformatics. All provided implementations are rigorously tested via continuous integration.

rustic_core - library for fast, encrypted, deduplicated backups that powers rustic-rs

A low-level, versioned, embedded, ACID-compliant, key-value database for Rust

Synchronization primitives built with portable-atomic.
