## What is Rust Programming Compiler?

Write Rust code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets!

Rust is a multi-paradigm system programming language focused on safety, especially safe concurrency. Rust is syntactically similar to C++, but is designed to provide better memory safety while maintaining high performance.

Features:
- Compile and run your program
- View program output or detailed error
- Select and run chunk of codes
- Custom keyboard for easy input of frequently used characters
- Optimized for connecting with external physical/bluetooth keyboard
- Advanced source code editor with syntax highlighting and line numbers
- Open, save, import and share rs files.
- Language reference

Limitations:
- Internet connection is required for compilation
- Maximum program running time is 20s
- Some file system, network and graphics functions may be limited
- This is a batch compiler; interactive programs are not supported. If your program provides an input prompt, enter the input in the Input tab prior to compilation. See the Reference tab in the app for code examples.

## Key features

- Compile and run Rust programs
- View program output and errors
- Select and run code chunks
- Custom keyboard for special characters
- Syntax highlighting and line numbers
- Open, save, import, and share files

### 5/5 — How to import crate

*2023-02-26*

Does anyone know how to add to the toml file? Can you post a review on how to if you do? Thanks!!

### 4/5 — Well done!

*2022-11-25, version 1.7*

I jeed to say overall this is half baked but it is insane that it exists. Well done I am amazed even this small portion of rust development and learning can be done here. Keep working on it and you will make the firt real rust app here. I just have a quick question: how can I open an existing rust file on the app ?

### 3/5 — Not there yet

*2022-07-09, version 1.6*

Needs documentation on how to import crate, save as, etc..

### 4/5 — Cool start

*2020-04-25, version 1.2*

This seems to work for small single-file projects, but it needs to make multi-file editing much easier. It doesn’t make starting a new project very easy. Git integration would also go a long way. 

All that said, I’m shocked that this even exists at all, so please keep working on it and making it more usable. I bought the full version just to support further development in some small way. I would definitely use it more if it made working with real world projects easier!

### 5/5 — Great app

*2020-03-18, version 1.2*

Amazing app, you can go to “reference” and see the rust by example or rust book, the complier works very well and is fast and easy.

### 5/5 — Nice!!!

*2019-11-23, version 1.0*

This is sick. Just got this and it seems like it works alright. Thanks for making this!
