Uses unquoted field names, trailing commas, and optional struct names, mirroring Rust code for improved readability and ease of writing, as shown in the example configs.

Implements Serde's data model to handle structs, enums, tuples, and more, enabling seamless integration with existing Rust serialization workflows.

Natively represents enums, Option types, and chars more succinctly than JSON, reducing verbosity and aligning with Rust's type system.

Supports comments and pretty-printing, making it ideal for configuration files and debugging, as demonstrated by the pretty RON output feature.
