Frequently Asked Questions
How do I run Rust code online in ZenCompiler?
Simply type or paste your Rust code into the editor, provide any optional inputs in the STDIN tab, and click the "Run" button (or press Ctrl/Cmd + Enter). Your code is executed inside a secure cloud Linux container with output streaming directly to the terminal.
Can I use ZenCompiler as an online rust compiler for mobile?
Yes! ZenCompiler is fully optimized as a mobile compiler online. You can code, edit, and run Rust on any mobile smartphone, iPhone, Android device, or tablet with responsive touch controls, virtual keyboard shortcuts, and full terminal input support without downloading any apps.
Which Rust compiler or runtime version is used?
ZenCompiler executes code using Rust (1.40), ensuring modern language standards, optimizations, and standard library support.
Does the online Rust compiler run the standard borrow checker?
Yes. The full official Rust compiler checks memory safety, ownership rules, and lifetime annotations.
Can I use Rust standard library collections like Vec and HashMap?
Yes. std::collections::HashMap, std::vec::Vec, std::sync, and all standard library modules are included.
