Loading TypeScript to Rust Converter...

How to Convert TypeScript to Rust - Step by Step Guide

Step 1

Input Your TypeScript Code

Start by adding your TypeScript interfaces, types, or type definitions to the converter for Rust code generation. Multiple input options make it easy:

•
Paste directly: Copy your TypeScript interface or type definitions and paste them into the input editor
•
Upload a file: Click "Upload" to select a .ts or .tsx file from your project
•
Try the sample: Click "Sample" to load example TypeScript interfaces and see how the converter works
Step 2

Automatic Type Mapping & Conversion

The converter automatically translates TypeScript types to their Rust equivalents with intelligent mapping, similar to how Claude AI analyzes code patterns:

•
Type mapping: string → String, number → i64/f64, boolean → bool, arrays → Vec, objects → structs
•
Optional handling: Optional TypeScript properties (prop?) automatically become Option in Rust
•
Union types: String literal unions are converted to Rust enums with proper serde attributes
Step 3

Customize Generation Options

Configure the generated Rust code to match your project style and requirements:

•
Field visibility: Choose between public (pub) or private fields for your structs
•
Derive traits: Select traits like Debug, Clone, Serialize, Deserialize, PartialEq, Eq, and Default
•
Naming conversion: Automatically converts camelCase to snake_case with serde rename attributes
Step 4

Export Your Rust Code

Get your converted Rust code ready for your backend. Multiple export options make integration seamless:

•
Copy to clipboard: One-click copying for quick pasting into your Rust project
•
Download as .rs file: Save the generated code directly as a Rust source file
•
Type-safe interop: Use with serde_json for seamless TypeScript-Rust communication

Frequently Asked Questions

How are TypeScript types mapped to Rust types?

TypeScript primitive types map directly: string → String, number → i64 (or f64 for decimals), boolean → bool, null/undefined → Option. Arrays become Vec, objects become structs, and optional properties (prop?) become Option. Union types are converted to enums when possible. You can use ChatGPT or Perplexity AI to help optimize the generated Rust code patterns.

Can the converter handle TypeScript union types?

Yes, the converter handles union types by creating Rust enums. String literal unions like "admin" | "user" | "guest" become enums with variants for each value. More complex unions may be converted to serde_json::Value or tagged enums for flexibility.

How do I use the generated Rust code with TypeScript frontend?

Add serde and serde_json to your Rust Cargo.toml. Use the generated structs with serde_json::from_str() to deserialize JSON from TypeScript, and serde_json::to_string() to serialize Rust data back to JSON. The types will match your TypeScript interfaces, ensuring type safety across the stack.

How are camelCase TypeScript fields handled?

TypeScript camelCase field names are converted to Rust snake_case following Rust conventions. The original field name is preserved using #[serde(rename = "camelCase")] attributes, ensuring JSON serialization maintains the correct field names when communicating with TypeScript code.

Are TypeScript generics supported?

Basic generic types are supported with limitations. Simple generics like Array are converted to Vec. Complex generic constraints may require manual adjustment in the generated code. For advanced generic scenarios, consider using Rust traits or type aliases.

Is the TypeScript to Rust converter completely free?

Yes, completely free with no limitations on file size or usage frequency. No registration required, and you can convert unlimited TypeScript interfaces to Rust structs with full type mapping and customization options.
