🦀 rustc Compiler Engine

Free Online Rust Compiler

Write, compile, and run Rust code online with rustc compiler, memory safety checking, cargo support, and Monaco editor.

💻 Code Example (Rust)

fn main() {
    println!("Hello, World from Online Rust Compiler!");
    
    let numbers = vec![1, 2, 3, 4, 5];
    let sum: i32 = numbers.iter().sum();
    println!("Sum of numbers: {}", sum);
}

Overview of Rust Compiler

Rust is a systems programming language focused on speed, memory safety, and safe concurrency without a garbage collector. Our Online Rust Compiler runs the rustc compiler in a secure Linux sandbox, allowing you to learn Rust ownership, borrowing, structs, pattern matching, and vectors without installing rustup or Cargo locally.

Key Platform Features

  • ⚡ Fast Sandbox Execution: Run code in under 2 seconds inside isolated Docker Linux containers.
  • 📝 Monaco Editor Engine: Experience auto-indentation, line numbers, and syntax highlighting powered by VS Code engine.
  • 📬 Interactive Stdin Input: Support for user input reading from stdin terminal interface.
  • 🔒 100% Secure & Private: Code runs purely in memory and is discarded after completion.
  • 📱 Zero Setup Required: Works seamlessly across laptops, tablets, and smartphones without downloads.

How to Compile & Run Code Online

  1. Select your preferred programming language from the top navigation bar.
  2. Type or paste your source code into the Monaco code editor.
  3. If your program requires user input, enter values into the interactive stdin terminal.
  4. Click the green Run Code button to compile and view your program output instantly.

Frequently Asked Questions (FAQ)

Q: Which Rust compiler toolchain is used?

Our Rust compiler uses stable rustc on a 64-bit Linux container.

Q: Does it check borrow checker and ownership errors?
