Loading Rust to TOML Converter...

How to Convert Rust to TOML - Step by Step Guide

Step 1

Input Your Rust Code

Start by adding your Rust struct definitions or data to the converter:

•
Paste directly: Copy your Rust struct code and paste it into the input editor
•
Upload a file: Click "Upload" to select a .rs file from your project
•
Try the sample: Click "Sample" to load example Rust code
Step 2

Automatic TOML Generation

The converter automatically parses your Rust code and generates clean TOML configuration:

•
Parses structs: Extracts field names and values from Rust struct definitions
•
TOML format: Generates proper TOML syntax with sections and key-value pairs
•
Preserves structure: Maintains nested objects as TOML sections
Step 3

Review Generated TOML

Review the generated TOML output with proper formatting:

•
Syntax highlighting: Review the generated TOML with proper color coding
•
Valid TOML: Output follows TOML specification and is ready to use
•
Real-time conversion: See changes instantly as you modify the Rust code
Step 4

Export Your TOML Configuration

Get your generated TOML ready for your project:

•
Copy to clipboard: One-click copying for quick use in config files
•
Download as .toml file: Save as Cargo.toml or any configuration file
•
Ready to use: Perfect for Rust project configuration, dependencies, and settings

Frequently Asked Questions

How does the Rust to TOML converter work?

The converter parses Rust struct definitions and extracts field names, types, and values. It then generates properly formatted TOML output following the official specification, with nested structs becoming TOML sections and arrays becoming TOML arrays.

What Rust types are supported?

The tool supports common Rust types including String, integers (i32, i64), floats (f32, f64), bool, Option types, Vec (arrays), and nested structs. These are converted to their TOML equivalents while maintaining the data structure.

Can I use this for Cargo.toml generation?

Yes! The generated TOML is valid and can be used in Cargo.toml files or any Rust project configuration. It's perfect for generating configuration files, dependency lists, and project settings in TOML format.

How are nested structs handled in TOML?

Nested Rust structs are converted to TOML tables. The converter uses dot notation or section headers [section.subsection] to represent the hierarchical structure, following TOML conventions for nested data.

Does this work with serde attributes?

The converter recognizes common serde attributes like #[serde(rename)] and uses the renamed field names in the TOML output. This ensures consistency between your Rust serialization configuration and the generated TOML.

Is the Rust to TOML converter free?

Yes, completely free with no limitations on usage or file size. No registration required, and you can convert unlimited Rust code to TOML format.
