Rust Converter
Convert JSON into Rust structs or translate simple Rust data models into TypeScript and Go. The converter includes inferred type mappings, serde-ready fields, warnings, and dependency guidance.

What this developer tool does
The converter parses supported data structures, maps primitive and collection types, generates nested declarations where possible, and reports ambiguous or unsupported types for manual review.
Parse source → detect selected structure → map field and collection types → generate target declarations → report warnings and required dependencies.
Generated types are starting points. Review nullable values, numeric ranges, dates, recursive data, custom generics, and serialization behavior.
Example
The page loads a working Rust Converter example. Run the tool to compare the sample input with the generated output and status summary.
Tips for better output
- Start with valid, isolated code or data.
- Review heuristic and inferred results manually.
- Use the official compiler, formatter, linter, or IDE before production use.
FAQ
How do I convert JSON to a Rust struct online?
Choose JSON to Rust Struct, paste valid JSON, enter a root type name, and run the converter.
How are null JSON values converted to Rust?
Null values are represented as optional values with a fallback inner type that should be reviewed manually.
Can I convert a Rust struct to TypeScript or Go?
Yes. The converter supports common primitive, vector, option, and map-like type patterns for simple struct declarations.
Can this browser tool replace the official compiler or IDE inspection?
No. It performs browser-based formatting, conversion, structural parsing, or heuristic analysis. Always verify production code with the official toolchain.
Does this tool upload my source code?
No processing is implemented by the page itself in your browser. Review your hosting and analytics configuration separately if you add external services.
