## What it is
RON (Rusty Object Notation) is a readable data serialization format that resembles Rust syntax and supports the full Serde data model, including structs, enums, tuples, maps, and ranges. It ships as a Rust crate providing a parser and serializer for the format, commonly used for game configs and other structured data files.

## Use cases
- serialize rust structs to a human-readable config file
- parse game configuration files in rust
- serde-compatible data format alternative to json
- read and write rust-like object notation files
- store enums and tuples in a config format
- deserialize nested structs and maps from text

## When to choose
- you want a config format that mirrors Rust syntax and Serde's data model
- you need enums, tuples, or ranges in your serialized data
- you want human-readable, comment-friendly config files for Rust or game projects

## When to avoid
- you need broad ecosystem interoperability with non-Rust tooling
- you need a widely standardized format like JSON, YAML, or TOML
- you need machine-generated data interchange across many languages

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser, configuration-management
- domain: developer-tools, files, programming-languages
- platform: rust, cross-platform
- tags: data-format, serde, config-format, rust-syntax, game-config, game-development
