Rust Playground Demo

1. Hello, World!

Try editing println! to print your name and hit Run.

2. With variables and mutability

3. Second example on same page — proves multiple embeds work

4. Error handling — see compiler output

Try running, then fix the error and run again.

5. Nightly + 2024 edition + release mode

6. Explicit component usage (import)

Static code stays static

This block is plain ````rustwithoutplayground` — it remains a highlighted, non-runnable code block:

fn main() {
    println!("This one is static — no Run button");
}

Fence syntax:

```rust playground title="My Example" edition=2024 channel=stable mode=debug
fn main() { println!("hi"); }
```

For MDX you can also use the component:

import { RustPlayground } from "@/components/ui/rust-playground";
<RustPlayground code={`fn main(){...}`} title="Example" />
