Overview

The theme provides Rust code demonstration functionality, supporting online execution of Rust code.

Important

This functionality works by submitting code to a server for compilation and execution, and only a single code file can be submitted at a time.

Therefore, please do not use this feature to execute overly complex code, and avoid making execution requests too frequently.

Configuration

This feature is disabled by default. You can enable it through configuration.

.vuepress/config.ts

export default defineUserConfig({
  theme: plumeTheme({
    markdown: {
      repl: {
        rust: true,
      },
    },
  })
})

Usage

Use the ::: rust-repl container syntax to wrap Rust code blocks. The theme will detect the code blocks and add execution buttons.

Read-only Code Demo

Rust code demos are read-only by default and cannot be edited.

::: rust-repl title="Custom Title"
```rust
// your rust code
```
:::

Editable Code Demo

For online editing and execution, wrap the code block in the ::: rust-repl editable container syntax.

::: rust-repl editable title="Custom Title"
```rust
// your rust code
```
:::

Examples

Print Content

Input:

::: rust-repl title="Print Content"
```rust
fn main() {
    println!("Hello, world!");
}
```
:::

Output:

Print Content

fn main() {
    println!("Hello, world!");
}

Click the Execute button to run the code.

Print Error Information

Input:

::: rust-repl
```rust
fn main() {
    printlnl!("Hello, world!");
}
```
:::

Output:

rust playground

fn main() {
    printlnl!("Hello, world!");
}

Wait for Child Process Execution

Input:

::: rust-repl
```rust
use std::process::Command;

fn main() {
    let mut child = Command::new("sleep").arg("5").spawn().unwrap();
    let _result = child.wait().unwrap();

    println!("reached end of main");
}
```
:::

Output:

rust playground

use std::process::Command;

fn main() {
    let mut child = Command::new("sleep").arg("5").spawn().unwrap();
    let _result = child.wait().unwrap();

    println!("reached end of main");
}

Editable Demo

Input:

::: rust-repl editable
```rust
fn main() {
    println!("Hello, world!");
}
```
:::

Output:

rust playground

fn main() {
    println!("Hello, world!");
}
