SIMD-accelerated CSV parser - drop-in replacement for Ruby's CSV library. Uses NEON on ARM64 and AVX2 on x86_64 for 2-6x faster parsing. Full API compatibility with CSV::Row, CSV::Table, converters, and all options.

A suite of instrumentation metric primitives that can be exposed through a web services interface.

This gem provides a helper for Vivarium to send USDT (User-level Statically Defined Tracing) events for method start and stop.

Wrapper of rust VTracer library, converter of raster images (like jpg & png) into vector graphics

Simple filesystem notification library for Ruby.

Ruby bindings for wesc's streaming HTML/web-component bundler. The Rust core runs in-process via a native extension — no subprocess, no WASM.

An ergonomic Ruby HTTP client powered by Rust's wreq library, featuring TLS fingerprint emulation (JA3/JA4), HTTP/2 support, cookie handling, proxy support, and redirect policies.

Ruby bindings for Wry........

Envoy x-forwarded-client-cert (XFCC) parser written in Rust for Ruby

Userland NAT64 implementation on Linux in Ruby

This gem helps to convert xml strings to json and vise versa

A Ruby wrapper for the Xoodyak cryptographic scheme, built in Rust using magnus and rb-sys. It supports hashing (unkeyed mode), symmetric encryption and AEAD (keyed mode), forward secrecy (state ratcheting), and integrates with the standard Ruby Digest API.

Ruby bindings (via Rust/magnus) for XXH3 — the modern XXH family from Yann Collet. Exposes both the 64-bit (XXH3_64bits) and the 128-bit (XXH3_128bits) variants through a Digest::Base-compatible API. Backed by the pure-Rust `xxhash-rust` crate, so there's no system-library runtime dependency.

The Stylo CSS parser wrapped in a Ruby embrace.

yrb-lite is a thread-safe Ruby binding over the Rust y-crdt (yrs) library: CRDT documents, awareness/presence, and the y-websocket sync protocol primitives, with the GVL released during native work so documents sync in parallel. The ActionCable/Rails integration lives in the companion yrb-lite-actioncable gem.

yrby is a thread-safe Ruby binding over the Rust y-crdt (yrs) library: CRDT documents, awareness/presence, and the y-websocket sync protocol primitives, with the GVL released during native work so documents sync in parallel. The ActionCable/Rails integration lives in the companion yrby-actioncable gem.

Ruby bindings (via Rust/magnus) for zrip, a pure-Rust Zstandard implementation. Frame-format and block-format compress/decompress with optional dictionary support, configurable compression levels, and FastCOVER-based dictionary training. Ractor-safe.
