How to Convert Rust to TOML - Step by Step Guide

Step 1

Input Your Rust Code

Start by pasting your Rust struct or data structure. Perfect for generating TOML configuration files and Cargo.toml settings.

•
Paste Rust code: Copy your Rust struct directly into the editor
•
Upload a file: Load Rust code from a .rs file on your computer
•
Try samples: Click sample buttons to see different Rust configuration patterns
Step 2

Click Convert Button

Click the green "Convert" button to transform your Rust code to TOML. Our backend API converts Rust syntax to proper TOML format with correct sections and key-value pairs.

•
Section headers: Rust nested structs become [section] and [section.subsection] headers
•
Key-value pairs: Rust struct fields convert to key = value TOML syntax
•
Array support: Rust vec! and arrays convert to TOML arrays with [item1, item2] syntax
•
Type handling: Proper conversion of i32, i64, f32, f64, bool, String, and nested structures
•
Comment preservation: Maintains data structure and field naming conventions
Step 3

Get Valid TOML Output

The tool produces properly formatted, valid TOML following TOML v1.0.0 specification. Ready for Cargo.toml, application configuration files, and Rust project settings.

Step 4

Copy or Download TOML

Copy the TOML to your clipboard or download it as a .toml file for use as Cargo.toml, config files, or application settings in your Rust projects.

What is Rust to TOML Conversion?

Rust to TOML conversion transforms Rust data structures into Tom's Obvious, Minimal Language format—the configuration format used by Cargo and many Rust applications. This process converts Rust structs into human-readable TOML configuration files with sections, tables, and key-value pairs.

The conversion is essential for Rust projects that need configuration files, especially Cargo.toml for dependency management. Using toml crate with Serde enables serialization, and this tool visualizes that output. You can also convert to other formats like Rust to JSON or Rust to YAML using our related tools.

Frequently Asked Questions

How do I convert Rust struct to TOML?

Simply paste your Rust struct into the converter. It automatically converts Rust syntax (structs, true/false, nested types) to valid TOML format with proper sections and key-value pairs. Perfect for generating configuration files.

Can I use this for Cargo.toml generation?

Yes! The generated TOML follows Cargo.toml specifications and can be used for dependency declarations, package metadata, build configurations, and project settings.

What Rust data types are supported?

The converter supports Rust structs, vecs, arrays, HashMap, strings, numbers (i32, i64, f32, f64), booleans (true/false), and Option types. These are converted to their TOML equivalents following the TOML v1.0.0 specification.

How are nested structs handled in TOML?

Nested Rust structs are converted to TOML tables using section headers like [section] and [section.subsection]. This maintains the hierarchical structure in a human-readable format.

How does this relate to toml crate in Rust?

This tool visualizes what toml::to_string() would produce when serializing your Rust structs with Serde. It helps preview TOML output before implementing serialization in your Rust code.

Is the Rust to TOML converter free?

Yes, completely free with no limitations on data size or conversion frequency. Perfect for Rust developers. No registration required.
