chromecast/browser/mojom

These mojo interfaces act as a frontend for the “Cast Browser”, a barebones content embedder targeting embedded devices such as Chromecast. All clients for these interfaces are fully trusted; the main client is the “Cast Service”, which hosts all of supporting logic for the Cast protocol. We never allow an untrusted process to use these interfaces (e.g. Chromium render processes).

The main interfaces in this folder are:

• CastWebService: Main entry point for browser initialization, creating/displaying pages, and mutating browser state.
• CastWebContents: Simplified wrapper for WebContents. Exposes a subset of content::WebContentsObserver events so that the client can respond to spontaneous page state changes, such as a page closing itself or crashing.
• CastContentWindow: Windowing logic for CastWebContents. This is backed by different window primitives depending on the platform, such as Android Activities/Fragments, aura::Window, or other system window embedder.
