Rustln
建议增加 `extern crate 包名` 说明，阅读很多开源项目，发现顶部都有此代码。 在 Rust 2015 版或更早版本需要这个导入语句，不过 Rust 2018 之后 99% 的情况下无需使用： 官方说明：https://doc.rust-lang.org/edition-guide/rust-2018/path-changes.html  **反正一句话解释：`extern crate xxx` 相当于现在的 `use xxx`。**  
看到比较好的解释： 
@Kangaxx-0 In Rust language, the following code is equivalent. ```rust let x = &1; ``` and ```rust let ref x = 1; ``` ----- ```rust let y = *x; ```...
Yes, in this case, `&` it doesn't seem necessary. Now I can't understand the author's motivation. Your question is right. Of course, you don't have to pay too much attention...
可以考虑使用 `Rust` 版本的 `Tauri`，[github](https://github.com/tauri-apps/tauri)
非常棒
