如何获知变量类型或者函数的返回类型

有几种常用的方式:

• 第一种是查询标准库或者三方库文档，搜索File，然后找到它的open方法，但是此处更推荐第二种方法:
• 在[Rust IDE]章节，我们推荐了VSCode IED和rust-analyze插件，如果你成功安装的话，那么就可以在VScode中很方便的通过代码跳转的方式查看代码，同时rust-analyze插件还会对代码中的类型进行标注，非常方便好用！
• 你还可以尝试故意标记一个错误的类型，然后让编译器告诉你:

#![allow(unused)]
fn main() {
let f: u32 = File::open("hello.txt");
}

错误提示如下：

error[E0308]: mismatched types
 --> src/main.rs:4:18
  |
4 |     let f: u32 = File::open("hello.txt");
  |                  ^^^^^^^^^^^^^^^^^^^^^^^ expected u32, found enum
`std::result::Result`
  |
  = note: expected type `u32`
             found type `std::result::Result<std::fs::File, std::io::Error>`
