Rust/WinRT快速入门

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 rustup which 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("hello world")?;
 
    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。
