Windows WebView2

The windows-webview crate is a safe Rust wrapper around the WebView2 COM APIs. It hosts the Microsoft Edge (Chromium) browser inside a window so you can render web content and run JavaScript from Rust.

WebView2 hosting requires a window and a running message loop. Environment and controller creation complete asynchronously on the UI thread, so the wrapper pumps the message loop for you and returns once each step is ready, letting you write the setup as straight-line code.

use windows_webview::*;
use windows_window::Window;

fn host(window: &Window) -> Result<()> {
    let environment = Environment::new()?;
    let controller = environment.create_controller(window)?;
    let webview = controller.webview()?;
    webview.navigate("https://github.com/microsoft/windows-rs")?;
    Ok(())
}

Key types: Environment, Controller, and WebView. The browser is hosted for as long as you keep the Controller alive. See the WebView2 guide for how this layer fits alongside reactor and canvas.
