示例

$ cat serde_json.rs
//# serde_json = "*"

use serde_json::{Result, Value};

fn main() -> Result<()> {
    // Some JSON input data as a &str. Maybe this comes from the user.
    let data = r#"
        {
            "name": "John Doe",
            "age": 43,
            "phones": [
                "+44 1234567",
                "+44 2345678"
            ]
        }"#;

    // Parse the string of data into serde_json::Value.
    let v: Value = serde_json::from_str(data)?;

    // Access parts of the data by indexing with square brackets.
    println!("Please call {} at the number {}", v["name"], v["phones"][0]);

    Ok(())
}

它还支持同时运行多个文件

$ cat tests/multi/entry.rs
mod hello;

fn main() {
    println!("Hello {}", hello::world());
}
$ cat tests/multi/hello.rs
pub fn world() -> String {
    "World".into()

Hello World

子目录下的文件将被复制并放置在第一个文件的相关位置。试试

cargo play tests/subdirs/**/*.rs

待办事项

• 编辑器插件
  • Vim
  • VS Code
• 工具链支持
• 版本支持

编辑器支持

Vim

将此行添加到您的.vimrc或init.vim

command! CargoPlay !cargo play %

当您的代码文件打开时，运行:CargoPlay将允许您在自动生成的Cargo项目中测试当前文件。

VSCode

安装VSCode扩展

或者

打开命令面板并选择配置任务

• 这将创建新的tasks.json或打开现有的tasks.json

添加以下任务

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "CargoPlay",
            "command": "cargo",
            "args": [
                "play",
                "${file}",
            ],
            "problemMatcher": [
                "$rustc"
            ]
        }
    ]
}

现在打开命令面板，选择运行任务，然后运行新的CargoPlay任务

Micro

将其添加到您的micro ~/.config/micro/init.lua

local config = import("micro/config")
local shell = import("micro/shell")

function init()
    config.TryBindKey("Alt-b", "lua:initlua.play", true)
    config.MakeCommand("cargoplay", play, config.NoComplete)
end

function play(bp)

    bp:Save()

    if bp.Buf:FileType() == "rust" then
        shell.RunInteractiveShell("cargo play " .. bp.Buf.Path, true, false)
    end
end

然后您可以按下 Alt + b 来 构建 当前文件，使用 cargo play，或者您可以使用 Ctrl + E 并在命令行中输入 cargoplay
