README

A Rust-powered PHP extension using ext-php-rs providing native implementations for performance-critical parts of the Flow DataFrame framework: encoding and decoding of the Floe binary format frames and row hydration/casting against a schema. The extension is optional — the pure-PHP implementations in flow-php/etl are the canonical behavior reference, and Flow routes to the native ones automatically when the extension is loaded.
