Crate webview2

Rust bindings for WebView2.

The new Chromium based Edge browser (>= 82.0.430.0) need to be installed for this to actually work. Or the build method will return an error.

By default, this crate ships a copy of the WebView2Loader.dll file for the target platform. At runtime, this dll will be loaded from memory with the memory-module-sys library. License of the DLL file (part of the WebView2 SDK) is included in the Microsoft.Web.WebView2.0.9.430 folder. You can also use an external WebView2Loader.dll file.

There are high level, idiomatic Rust wrappers for most APIs. And there are bindings to almost all the raw COM APIs in the webview2-sys crate. You can use the as_inner methods to convert to raw COM objects and call all those methods. The callback macro can be helpful for implementing callbacks as COM objects.

Macros

callback

Returns a pointer that implements the COM callback interface with the specified closure. Inspired by C++ Microsoft::WRT::Callback.
