  2. Click the convert button.
  3. The resulting Rust code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from F# to Rust using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Example 1 - Is String Palindrome

Program that checks if a string is a palindrome or not.

Key differences between F# and Rust

CharacteristicF#Rust
SyntaxF# has a functional-first syntax with support for imperative and object-oriented programming.Rust has a syntax inspired by C and C++, with a focus on memory safety and concurrency.
ParadigmF# supports functional, imperative, and object-oriented programming paradigms.Rust supports imperative and functional programming paradigms, with a focus on safety and concurrency.
TypingF# is a statically typed language with type inference.Rust is a statically typed language with strong type inference and ownership system.
PerformanceF# provides good performance and interoperability with .NET ecosystem.Rust is designed for high-performance systems programming with low-level control over resources.
Libraries and frameworksF# has access to the extensive .NET ecosystem, including libraries and frameworks.Rust has a growing ecosystem of libraries and frameworks, but it is not as extensive as some other languages.
Community and supportF# has an active and supportive community with good documentation and tooling.Rust has a growing community with good documentation and tooling, backed by Mozilla.
Learning curveF# has a moderate learning curve, especially for developers familiar with functional programming.Rust has a steep learning curve due to its unique ownership system and focus on memory safety.

Frequently Asked Questions

How do I convert F# to Rust?

Paste your F# code into the input box, confirm the languages are set to F# and Rust, and click Convert. CodeConvert AI analyzes your F# code and generates equivalent Rust code in seconds, preserving the original logic and structure.

What are the main differences between F# and Rust?

F# and Rust differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each F# construct to its closest Rust equivalent. See the comparison table below for the key differences between F# and Rust.

Is the converted Rust code accurate?

The AI produces high-quality Rust code that preserves the behavior of your original F# code and follows Rust conventions. It handles common patterns, data structures, and idioms for both F# and Rust. For large or performance-critical code, review and test the Rust output before using it in production.

Can I convert an entire F# project to Rust?

You can convert F# files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from F# to Rust. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.

Can I convert Rust back to F#?

Yes. CodeConvert AI converts in both directions, so you can convert Rust to F# just as easily using our Rust to F# converter. Try the Rust to F# Converter

Is the F# to Rust converter free, and do I need to install anything?

Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert F# to Rust without an account for up to 5 conversions per day. Sign in for free for higher limits.

What are the benefits of signing in?

Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
