How do I convert Kotlin code to Rust using this online converter?

Simply paste your Kotlin source code into the left editor, choose Rust as the output language, and press the 'Convert' button. The tool automatically translates Kotlin constructs—like data classes to structs, sealed classes to enums, and nullable types to Option or Result—and delivers Rust code you can copy or download. For complex projects, we recommend converting file-by-file to review the output.

Why would a developer convert Kotlin to Rust instead of keeping it in Kotlin?

Kotlin runs primarily on the JVM, which brings garbage collection and a large runtime footprint. Rust compiles to native code with no runtime and uses an ownership model to guarantee memory safety and thread safety without a GC. Converting to Rust is ideal for systems programming, WebAssembly, embedded devices, or any scenario where performance and resource usage are critical. You also gain the ability to reuse existing Kotlin logic in a Rust-based codebase.

How does the converter handle Kotlin-specific features like coroutines, companion objects, and nullable types?

The conversion preserves the semantic meaning of these features. Nullable types (e.g., String?) become Option or Result , which enforces explicit error handling. Coroutines are mapped to async/await with the Tokio runtime, while companion objects are translated to associated functions and constants in Rust. Extension functions become trait implementations or inherent methods. The output is designed to be idiomatic Rust, though some manual refactoring may be necessary for advanced generics or reflection.
