Trait WebViewBackend 

pub trait WebViewBackend {
    // Required method
    fn open(
        &mut self,
        web_view_id: WebViewId,
        window_id: TeksiloWindowId,
        parent: Option<ParentHandle>,
        attrs: WebViewAttributes,
        poster: Option<Arc<dyn AppEventPoster>>,
    ) -> Box<dyn WebViewHandle>;
}

Swappable web-view engine backend.

The real backends (WryBackend / ServoBackend, behind their features) create a native engine subview parented to the host window. The test backend (MemoryWebViewBackend) records calls and synthesizes events.

Required Methods

fn open( &mut self, web_view_id: WebViewId, window_id: TeksiloWindowId, parent: Option<ParentHandle>, attrs: WebViewAttributes, poster: Option<Arc<dyn AppEventPoster>>, ) -> Box<dyn WebViewHandle>

Create a native engine subview for web_view_id, parented to window_id’s OS window. The backend MUST deliver browser events by calling AppEventPoster::post_external on poster with a boxed WebViewEventPayload whose web_view_id / window_id_owner match.

parent is None when the host context can’t surface an OS handle (headless tests, or a build-time open before the window-ops sink is available); native backends treat None as “defer until a handle arrives” rather than failing hard.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
