Ruby bindings (via Rust/magnus) for liblz4, using lz4-sys FFI. Provides block-format and frame-format LZ4 compress/decompress with optional dictionary support. Designed to be safe to call from multiple Ractors, unlike existing Ruby LZ4 gems.

Embed and verify C2PA content provenance and authenticity credentials in images, video, and audio files. Ruby bindings for the official Rust c2pa-rs library.

Finite state transducer backed ordered sets and maps via the Rust fst crate by BurntSushi

A Ruby gem that compiles a native Rust extension with magnus and rb-sys to expose Turbovec APIs.

This gem brings in a rust library (RQRR) to detect QR codes in images.

A V8 engine for Ruby built on rusty_v8 and Magnus: eval, host functions, ES modules, snapshots, realms, bytecode cache, faithful value marshalling, and an ExecJS adapter.

Ruby bindings (via Rust/magnus) for the Zstandard compressor with persistent ZSTD_CCtx / ZSTD_DCtx contexts that are reused across calls. Provides Zstd frame compress/decompress at module level and a stateful Dictionary class for dict-bound compression. Designed to be safe to call from multiple Ractors and competitive with rlz4 on small messages, where per-call context allocation in zstd-ruby dominates the cost.

An unofficial Ruby wrapper for Tiktoken, a BPE tokenizer written by and used by OpenAI. It can be used to count the number of tokens in text before sending it to OpenAI APIs. This is a fork of tiktoken_ruby by IAPark, which has been cross-compiled for multiple platforms. This way compilation with Rust extensions doesn't need to happen wherever you are deploying it.

Simple, safe way to store and distribute tensors

Embeddable, dependency-free SCSS/Sass compiler aiming at byte-for-byte dart-sass parity, shipped as a Rust native extension (magnus + rb-sys).

Populate environment variables with secrets only when you need them.
