How to Convert Rust to JSON Schema - Step by Step Guide

Step 1

Input Your Rust Code

Start by adding your Rust struct definitions to the converter:

•
Paste directly: Copy your Rust struct definitions and paste them 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 struct code
Step 2

Automatic JSON Schema Generation

The converter automatically parses your Rust code and generates JSON Schema:

•
Schema definition: Generates JSON Schema with type definitions
•
Property mapping: Converts Rust fields to JSON Schema properties
•
Validation rules: Includes required fields and type constraints
Step 3

Review Generated JSON Schema

Review the generated JSON Schema with syntax highlighting:

•
Syntax highlighting: Review the schema with proper color coding
•
Draft 7 compliant: Output follows JSON Schema Draft 7 specification
•
Real-time conversion: See changes instantly as you modify the Rust code
Step 4

Export Your JSON Schema

Get your generated JSON Schema ready for use:

•
Copy to clipboard: One-click copying for quick use in your APIs
•
Download as .json file: Save schema for validation libraries
•
Ready to use: Perfect for API validation, documentation, OpenAPI specs, and form generation

Frequently Asked Questions

How does the Rust to JSON Schema converter work?

The converter parses Rust struct definitions and generates JSON Schema definitions. It maps Rust types to JSON Schema types, includes required fields, and generates validation rules for API documentation and data validation.

What is JSON Schema used for?

JSON Schema is used for validating JSON data structures, generating API documentation, creating OpenAPI specifications, auto-generating forms, and ensuring data consistency across systems.

How are Rust types mapped to JSON Schema?

Rust types map to JSON Schema types: String becomes "string", integers become "integer", floats become "number", bool becomes "boolean", Option types make fields non-required, Vec becomes "array", and nested structs become "object" with nested properties.

Can I use this for API documentation?

Yes! The generated JSON Schema is perfect for API documentation. It works with Swagger/OpenAPI, API documentation generators, and validation libraries to automatically document your Rust-based APIs.

Does this work with serde attributes?

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

Is the Rust to JSON Schema converter free?

Yes, completely free with no limitations on usage or file size. No registration required, and you can generate unlimited JSON Schemas from your Rust structs for any project.
