How to Convert Rust to GraphQL 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 GraphQL Schema Generation

The converter automatically parses your Rust code and generates GraphQL schema:

•
Type definitions: Generates GraphQL type definitions
•
Field mapping: Converts Rust fields to GraphQL fields
•
Type mapping: Includes scalar and complex GraphQL types
Step 3

Review Generated GraphQL Schema

Review the generated GraphQL schema with syntax highlighting:

•
Syntax highlighting: Review the schema with proper color coding
•
GraphQL syntax: Output follows GraphQL SDL specification
•
Real-time conversion: See changes instantly as you modify the Rust code
Step 4

Export Your GraphQL Schema

Get your generated GraphQL schema ready for use:

•
Copy to clipboard: One-click copying for quick use in your APIs
•
Download as .graphql file: Save schema for GraphQL servers
•
Ready to use: Perfect for GraphQL APIs, Apollo Server, resolvers, and client code generation

Frequently Asked Questions

How does the Rust to GraphQL Schema converter work?

The converter parses Rust struct definitions and generates GraphQL schema definitions. It maps Rust types to GraphQL types, creates type definitions, and generates a complete GraphQL schema for your API.

What is GraphQL Schema used for?

GraphQL schema defines the structure of your API, including types, queries, and mutations. It enables type-safe API development, auto-generated documentation, client code generation, and efficient data fetching.

How are Rust types mapped to GraphQL?

Rust types map to GraphQL types: String becomes String, integers become Int, floats become Float, bool becomes Boolean, Option types make fields nullable, Vec becomes lists, and nested structs become nested types.

Can I use this for GraphQL APIs?

Yes! The generated GraphQL schema works with Apollo Server, GraphQL servers, and schema-first development workflows. You can use it to define your API structure and generate resolvers.

Does this work with serde attributes?

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

Is the Rust to GraphQL Schema converter free?

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