The windows-app crate lets you call any Windows App SDK (formerly known as Project Reunion) API using code generated from the metadata describing the API. It is powered by the windows crate.
Note: This is an experimental 🧪 crate and is not ready for production use.
The Windows App SDK is delivered via three release channels—experimental, preview, and stable. The windows-app crate currently targets APIs available in the preview and stable channels.
It's very early days for the windows-app crate. To try it out, add the following to your Cargo.toml file:
[build-dependencies.windows-app]
git = "https://github.com/microsoft/windows-app-rs"
features = [
"WindowsAppSdk_Foundation"
]
[dependencies.windows]
version = "0.35.0"
[dependencies.windows-app]
git = "https://github.com/microsoft/windows-app-rs"
features = [
"WindowsAppSdk_Foundation",
"Windows_System_Power"
]Add a build script (build.rs) to your crate to deploy the Windows App SDK Bootstrapper with your app:
fn main() {
::windows_app::bootstrap::deploy::to_output_dir();
}Now make use of any Windows App SDK APIs as needed:
use ::windows_app::Microsoft::Windows::System::Power::*;
use ::windows_app::*;
fn main() -> ::windows::core::Result<()> {
bootstrap::initialize()?;
let charge = PowerManager::RemainingChargePercent()?;
println!("Remaining charge: {charge}%");
bootstrap::uninitialize()
}Finally, install the Windows App Runtime on all target machines:
- Download the Windows App Runtime Redistributable package.
- Execute
WindowsAppSDK-Installer-{arch}\WindowsAppRuntimeInstall.exe.
After you install the Windows App Runtime, it will be kept up-to-date by Microsoft via Windows Update.
