Rust Webkit2GTK Ping Pong Example

  Discontinued [UNMAINTAINED] WebKit2 bindings and wrappers for Rust

  

I am creating a desktop app based on webkit2gtk-rs. I am having a problem with sending data back to the UI after calling:

• web-view

  9 1,894 2.3 JavaScript

  Rust bindings for webview, a tiny cross-platform library to render web-based GUIs for desktop applications

I want get a pong back from the app process, but I cant figure out how. I do aware of Boscop Webview and webview_official, but I want to work with Webkit2GTK to have more controls. I really appreciate your kind help.
