Introduction

omnist is one canonical data model for JSON, YAML, TOML, XML, and its own native OML, plus a schema language (OSD) to validate and compare shapes over that model. This book is the Rust port’s documentation (the crate is omnist, CLI is omnist-cli).

Start with the Quickstart, then read the user guide for the full model. The CLI reference covers the omnist binary, and each entry under Formats documents one codec’s specific round-trip behavior.

This is the Rust port of omnist. See Python divergences for where the two implementations differ, and Limitations & stability for the current alpha-status caveats.
