Getting started with Rust/WinRT https://kennykerr.ca/2020/06/05/getting-started-with-rust-winrt/
加拿大小伙子Kenny Kerr写的Rust/WinRT编程快速入门。
Rust/WinRT编程快速入门已经非常简单，这得益于程序员喜欢的Rust语言编程工具链提供了大量的便利。如果你想不需要额外的帮助直接入门，下面是一些有用的链接
- GitHub: https://github.com/microsoft/winrt-rs
- Docs.rs: https://docs.rs/winrt/
- Crates.io: https://crates.io/crates/winrt
下面会给一些个人的心得和小技巧：
安装先决条件和工具：
- Visual Studio 2019 – be sure to install the C++ tools as this is required by the Rust compiler (only the linker is required).
- Visual Studio Code – this is the default IDE used for Rust.
- Python – be sure to install the x64 version as this is required for debugging support.
- Git – Rust has deep support for Git.
- Rust – this installs
rustupwhich is a tool for installing Rust toolchains and common Rust related tooling.
打开VS Code然后键入Ctrl+Shift+X打开扩展页安装下面的extensions:
- rust-analyzer – there are others, but this is the only Rust extension that I’ve tried that actually works reliably most of the time.
- CodeLLDB – you can also use the Microsoft C++ extension for debugging, but this one does a better job of integrating with the IDE.
- C/C++ – the Microsoft C++ extension doesn’t integrate as well with the IDE, but provides superior debugging information, so you may want to have that on hand for an emergency.
提示下载并安装Rust language server，确认安装，然后重新启动IDE。然后我们开始用新的cargo包创建例子：
C:\>cargo new sample
Created binary (application) `sample` package
C:\>cd sample
C:\sample>code .新创建的项目目录下修改Cargo.toml配置文件，并添加WinRT的依赖库包：
[dependencies]
winrt = "0.7.0"确认所有的库是最新的，然后开始编译项目：
C:\sample>cargo build
Updating crates.io index
Compiling proc-macro2 v1.0.18
Compiling unicode-xid v0.2.0
...
Compiling winrt_gen_macros v0.7.0
Compiling winrt_gen v0.7.0
Compiling winrt_macros v0.7.0
Compiling winrt v0.7.0
Compiling sample v0.1.0 (C:\sample)
Finished dev [unoptimized + debuginfo] target(s) in 19.65s
C:\sample>cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.06s
Running `target\debug\sample.exe`
Hello, world!在项目文件夹里找到写hello world的源文件main.rs，我们用winrt::import macro来生成Rust bindings for WinRT的APIs：
winrt::import!(
dependencies
os
types
windows::data::xml::dom::*
);其实你在main.rs里面任何位置放置上面的代码都可以，这个导入的宏分成两个部分：一类是你的项目中需要标识WinRT组件，另一类是特别需要相应的类型子集。这里用了os表示需要运行的操作系统，也可以指定特定版本的Windows SDK。然后指定了官方文档中的一些类型windows::data::xml::dom 下面还有用了XmlDocument，具体的细节可以参考官方文档:
fn main() -> winrt::Result<()> {
use windows::data::xml::dom::*;
let doc = XmlDocument::new()?;
doc.load_xml("<html>hello world</html>")?;
let root = doc.document_element()?;
assert!(root.node_name()? == "html");
assert!(root.inner_text()? == "hello world");
Ok(())
}编译运行的结果：
C:\sample>cargo run
Compiling sample v0.1.0 (C:\sample)
Finished dev [unoptimized + debuginfo] target(s) in 8.71s
Running `target\debug\sample.exe`这样，import宏导进来的库就可以开始调用指定的Windows API了。
