Tyfoom's fork of the `parquet` gem (github.com/njaremko/parquet-ruby), published while the incremental streaming-write fix is pending upstream. It wraps the official Apache Rust implementation and bounds write memory by streaming row groups to disk instead of buffering the whole file. Drop-in compatible with the upstream gem: the library is still required as `require "parquet"` and exposes the same `Parquet` API.

A small Ruby library for constructing parsers in the PEG (Parsing Expression Grammar) fashion. Parsanol provides Parslet-compatible API with additional features including static frozen parsers and dynamic parsers, with optional Rust native extension for improved performance.

Tools for working with the International Phonetic Alphabet. Two-tier distance API — strict acoustic and listener-perception — backed by a Rust core compiled in via Magnus. Calibrated against Mad Gab puzzle data and English speech-perception literature.

High-performance phrase matching using Aho-Corasick automaton with Ruby bindings via Magnus

PiiCipher lets you search encrypted PII columns in ActiveRecord without ever storing or querying plaintext. It generates HMAC-SHA256 blind indexes alongside your ciphertext — trigram arrays for partial (substring) searches and single hashes for exact-match lookups. The hash functions run in a native Rust extension for performance. Query interception is transparent: call `where` as normal and PiiCipher rewrites the query against the blind index automatically.

Code verifier and challenge generator for use in PKCE Oauth2.
