在git上下载了一个rust项目，使用了winapi

代码段： extern crate gdi32; extern crate user32; use winapi::{ RECT, SW_SHOW}; use winapi::winnt::{ LPCWSTR, HANDLE }; use winapi::minwindef::{UINT, DWORD, WPARAM, LPARAM, LRESULT, HINSTANCE };

编译出现

Compiling sweepers v0.1.0 (file:///E:/mywork/rust/sweepers) error[E0432]: unresolved import winapi::RECT --> src\devices.rs:3:15 | 3 | use winapi::{ RECT, SW_SHOW}; | ^^^^ no RECT in the root

查资料：https://docs.rs/winapi/*/x86_64-pc-windows-msvc/winapi/shared/windef/index.html 发现是Module winapi::shared::windef

于是代码修改为： extern crate gdi32; extern crate user32;

use winapi::shared; use winapi::shared::windef; use winapi::shared::windef::RECT;

编译出现 Compiling sweepers v0.1.0 (file:///E:/mywork/rust/sweepers) error[E0432]: unresolved import winapi::shared::windef --> src\devices.rs:5:5 | 5 | use winapi::shared::windef; | ^^^^^^^^^^^^^^^^^^^^^^ no windef in shared

error[E0432]: unresolved import winapi::shared::windef --> src\devices.rs:6:21 | 6 | use winapi::shared::windef::RECT; | ^^^^^^ Could not find windef in shared

我是差了什么东西吗？

https://crates.io/crates/winapi 提到过 Windows 10 SDK 这个东西，难道需要安装这个？
