Rust playground

Welcome to TypeRust! This is a simple Rust playground where you can build or run your Rust code and share it with others.

There are a few things to keep in mind before using it:

• Code execution time is limited and if it takes too long to complete it will be interrupted.
• Your program cannot use too much memory. If it exceeds the limit it will be interrupted.
• Since the program runs in a sandbox, it doesn't have access to filesystem and/or network. Of course simply building code is fine.

Environment

• The code is compiled to wasm32-wasi target and is run in a wasmtime instance.
• The latest stable version of Rust with 2021 edition is used.
• There is no way to install crates (yet).

Development

Tech

TypeRust playground is powered by Svelte and CodeMirror editor on frontend and axum (and its ecosystem) on backend. wasmtime is used to create ephemeral WASM virtual machines to run user code. The whole thing is deployed to Fly.io.

Source code

You can find source code on Github: https://github.com/jlkiri/typerust.
