What is a RON file?

A RON file is a plain text file that contains data written using Rusty Object Notation. Rusty Object Notation is a data serialization format that is similar to JSON but uses syntax from the Rust programming language.

Just like JSON, Rusty Object Notation can be used to structure and transmit data. Unlike JSON files, RON files can include trailing commas and single- and multi-line comments, and they can include struct labels that group sets of data.

Most often, RON files are referenced within Rust programs. To use a RON file with a Rust program, a developer must add Rusty Object Notation as a dependency and then import the RON file.

How to open a RON file

You can open and edit a RON file in any text or source code editor. Source code editors, such as Microsoft Visual Studio Code and GitHub Atom, include helpful syntax-highlighting and code-editing tools that make reading and editing RON files easier.
