## 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:
|
|
|
|
```rust
|
|
let f: u32 = File::open("hello.txt");
|
|
```
|
|
错误提示如下：
|
|
|
|
```console
|
|
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>`
|
|
```
