About JSON to Rust Converter
The JSON to Rust converter uses `quicktype-core` to generate Rust `struct` definitions with `#[derive(Serialize, Deserialize)]` macros for use with `serde_json`. A post-processing step strips boilerplate helpers. Output is prettified with js-beautify. The UML class diagram panel shows the inferred struct hierarchy.
Features
- ✓Powered by quicktype-core for Rust struct generation
- ✓Generates structs with #[derive(Debug, Serialize, Deserialize)] macros
- ✓serde field attributes (#[serde(rename...)]) for non-snake_case keys
- ✓Post-processed to remove boilerplate helpers
- ✓UML class diagram view shows the inferred struct hierarchy
- ✓Handles nested objects → nested Rust structs
- ✓Handles arrays → Vec<T> field types
- ✓Optional fields use Option<T>
- ✓Download generated Rust as a .rs file
- ✓Copy output to clipboard in one click
- ✓Web Worker processing — never blocks the UI
- ✓100% client-side — data never leaves your browser
Common Use Cases
- Generating Rust structs from JSON API responses for typed serde_json parsing
- Creating Rust data models from JSON schemas for Actix-web or Axum handlers
- Scaffolding Rust types from JSON configuration files
- Reverse-engineering JSON payloads to Rust struct definitions
Frequently Asked Questions
QDoes the output include serde imports?
Yes — the output includes use serde::{Serialize, Deserialize}; and requires the serde and serde_json crates in Cargo.toml.
QIs my data sent to a server?
No. quicktype-core runs in a Web Worker inside your browser.
