Rewrite rules cover 13 source and 13 target languages (Python, JavaScript, TypeScript, Java, C#, Go, Ruby, PHP, Rust, Kotlin, Swift); the remaining 31 are listed for reference and pass through annotated rather than translated. Complex projects still need manual review — all processing runs locally in your browser.

About C++ to Rust Converter

C++ to Rust Code Converter

Port algorithms, interview snippets, and learning examples from C++ to Rust without installing compilers or online APIs. ToolSphere runs conversion logic locally so proprietary or assignment code stays private.

Typical use cases: migrating utility scripts, comparing syntax across languages, preparing Rust stubs from C++ prototypes, and speeding up CS homework refactoring.

Select your languages, paste code, and iterate with swap-and-edit until the output matches your target idioms.

C++ to Rust converts through JavaScript. There are no direct C++-to-Rust rules, so the converter translates C++ into JavaScript first and then emits Rust. Structure and control flow survive that round trip; types and idioms usually need a pass by hand afterwards.

Frequently Asked Questions

Why does the output need review for C++ to Rust?

This pair is converted in two steps via JavaScript, which has no static types. Declarations that were precise in C++ come out inferred in Rust, so check types, numeric widths and imports before compiling.

Is my source code uploaded to a server?

No. Conversion runs entirely in your browser with JavaScript. Your code never leaves your device.

How accurate is automatic code conversion?

Popular pairs (Python, JavaScript, Java, Go, C#, etc.) use dedicated rewrite rules. Other pairs may use a JavaScript pivot or annotated passthrough — always review before production use.

Can I convert entire projects?

This tool is optimized for snippets, homework samples, and algorithm ports. Multi-file projects need manual structure and import adjustments.

Does this support every C++ library?

No. Standard language syntax is mapped; framework-specific APIs must be rewritten manually in Rust.
