What Can the cURL to Rust Code Generator Do?

The cURL to Rust Code Generator is an online tool for Rust developers that automatically converts cURL commands into Rust HTTP client code. When you need to replicate existing cURL requests in Rust, this tool saves you from manually writing HTTP client code by generating ready-to-run Rust code with one click.

Core Features

• Dual Library Support: Supports reqwest (async, most popular) and ureq (sync, lightweight) Rust HTTP libraries
• Complete Option Parsing: Auto-parses -X, -H, -d, -F, -u, -b, -k and other cURL options
• Smart JSON Handling: Detects JSON request bodies and auto-generates serde structs and .json() method calls
• Auth Support: Auto-handles Bearer Token and Basic Auth authentication headers
• Full Project Output: Option to generate complete projects with main function and Cargo.toml dependencies

How to Use

1. Paste your cURL command in the input box, or click "Load Example" for a demo; 2. Select HTTP library (reqwest/ureq) and code style; 3. The tool auto-generates Rust code in real-time; 4. Click "Copy" to copy the code; 5. Use in your Rust project or download as .rs file.

Use Cases

Case 1: API Debug to Code

After debugging an API with cURL in the terminal, use this tool to convert it to Rust code for direct integration into your project.

Case 2: Documentation Example Conversion

API docs typically only provide cURL examples. Use this tool to quickly convert them to Rust code and accelerate development.

Case 3: Web Scraper Development

Copy browser DevTools requests as cURL, then convert to Rust code for building web scrapers.

Extended Knowledge

reqwest is the most popular HTTP client library in the Rust ecosystem, built on hyper and tokio, supporting async requests, connection pooling, cookies, proxies, and TLS. ureq is a lightweight synchronous HTTP client that doesn't require an async runtime, ideal for simple scripts and embedded scenarios. Both support JSON request/response (with serde_json), form submission, file upload, and other common HTTP operations. reqwest defaults to rustls as the TLS backend but can switch to native-tls.
