The windows-future crate provides stock async support for Windows APIs.

• Getting started
• Samples
• Releases

Start by adding the following to your Cargo.toml file:

[dependencies.windows-future]
version = "0.1"

Use the Windows async types as needed:

use windows_future::*;
use windows_result::*;

fn main() -> Result<()> {
    // This result will be available immediately.
    let ready = IAsyncOperation::ready(Ok(123));
    assert_eq!(ready.get()?, 123);

    let ready = IAsyncOperation::spawn(|| {
        // Some lengthy operation goes here...
        Ok(456)
    });

    assert_eq!(ready.get()?, 456);

    Ok(())
}
