the core is https://github.com/webview/webview with its rust binding, electron binds chromium and nodejs, I don't really know how webview works, a thin cross-platform API wrapper layer on top of native browser engine for each OS, so that you leverage the pre-installed browser in the OS and use it kind of like a shared library to minimize the app size?

electron always bundles the whole chromium into its binary, what is exactly "webview" comparing to chromium inside electron app?
