## 概述
|
|
|
|
主题提供了 Rust 代码演示,支持 在线运行 Rust 代码。
|
|
|
|
::: important
|
|
该功能通过将 代码提交到 服务器 进行 编译并执行,且一次只能提交单个代码文件。
|
|
|
|
因此,请不要使用此功能 执行 过于复杂的代码,也不要过于频繁的进行执行请求。
|
|
:::
|
|
|
|
## 配置
|
|
|
|
该功能默认不启用,你可以通过配置来启用它。
|
|
|
|
::: code-tabs
|
|
@tab .vuepress/config.ts
|
|
|
|
```ts
|
|
export default defineUserConfig({
|
|
theme: plumeTheme({
|
|
plugins: {
|
|
markdownPower: {
|
|
repl: {
|
|
rust: true,
|
|
},
|
|
},
|
|
}
|
|
})
|
|
})
|
|
```
|
|
|
|

|
|
|
|
## 使用
|
|
|
|
使用 `::: rust-repl` 容器语法 将 Rust 代码块包裹起来。主题会检查代码块并添加执行按钮。
|
|
|
|
### 只读代码演示
|
|
|
|
rust 代码演示默认是只读的,不可编辑。
|
|
|
|
````md
|
|
::: rust-repl 自定义标题
|
|
```rust
|
|
// your rust code
|
|
```
|
|
:::
|
|
````
|
|
|
|
### 可编辑代码演示
|
|
|
|
如果需要在线编辑并执行,需要将代码块包裹在 `::: rust-repl#editable` 容器语法中
|
|
|
|
````md
|
|
::: rust-repl#editable 自定义标题
|
|
```rust
|
|
// your rust code
|
|
```
|
|
:::
|
|
````
|
|
|
|
## 示例
|
|
|
|
### 打印内容

|
|
**输入:**
|
|
|
|
````md
|
|
::: rust-repl 打印内容
|
|
```rust
|
|
fn main() {
|
|
println!("Hello, world!");
|
|
}
|
|
```
|
|
:::
|
|
````
|
|
|
|
**输出:**
|
|
|
|
::: rust-repl 打印内容
|
|
|
|
```rust
|
|
fn main() {
|
|
println!("Hello, world!");
|
|
}
|
|
```
|
|
|
|
:::

|
|
**输入:**
|
|
|
|
````md
|
|
::: rust-repl
|
|
```rust

|
}
|
|
```
|
|

### 等待子进程执行
|
|
|
|
**输入:**
|
|
|
|
````md
|
|
::: 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");
|
|
}
|
|
```
|
|
:::
|
|
````
|
|
|
|
**输出:**
|
|
|
|
::: 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");
|
