Language comparison
Key differences between Rust and Gleam
| Characteristic | Rust | Gleam |
|---|---|---|
| Syntax | C-like syntax with curly braces, explicit variable declarations, and pattern matching. | Erlang/ML-inspired syntax, indentation-based, concise and functional. |
| Paradigm | Multi-paradigm: systems programming, imperative, functional, and concurrent. | Purely functional, designed for reliability and simplicity, targets BEAM VM. |
| Typing | Statically typed with strong type inference and zero-cost abstractions. | Statically typed with type inference, focuses on simplicity and safety. |
| Performance | High performance, comparable to C/C++, suitable for low-level systems. | Runs on BEAM VM, performance similar to Erlang/Elixir, optimized for concurrency, not raw speed. |
| Libraries and frameworks | Rich ecosystem with crates.io, mature libraries for web, networking, and systems. | Smaller ecosystem, can use Erlang/Elixir libraries, but fewer native Gleam libraries. |
| Community and support | Large, active community, strong documentation, and corporate backing. | Growing but smaller community, good documentation, mostly grassroots support. |
| Learning curve | Steep learning curve due to ownership, lifetimes, and advanced features. | Gentle learning curve, simple syntax, and functional concepts, easier for beginners. |
Common questions
Frequently Asked Questions
How do I convert Rust to Gleam?
Paste your Rust code into the input box, confirm the languages are set to Rust and Gleam, and click Convert. CodeConvert AI analyzes your Rust code and generates equivalent Gleam code in seconds, preserving the original logic and structure.
What are the main differences between Rust and Gleam?
Rust and Gleam differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Rust construct to its closest Gleam equivalent. See the comparison table below for the key differences between Rust and Gleam.
Is the converted Gleam code accurate?
The AI produces high-quality Gleam code that preserves the behavior of your original Rust code and follows Gleam conventions. It handles common patterns, data structures, and idioms for both Rust and Gleam. For large or performance-critical code, review and test the Gleam output before using it in production.
Can I convert an entire Rust project to Gleam?
You can convert Rust 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 Rust to Gleam. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Gleam back to Rust?
Yes. CodeConvert AI converts in both directions, so you can convert Gleam to Rust just as easily using our Gleam to Rust converter. Try the Gleam to Rust Converter
Is the Rust to Gleam 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 Rust to Gleam 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.
