5//! A gooey [`Interface`] is defined as a layer between an [`Application`] and a
6//! [`Presentation`] backend.
7//!
8//! An `Application` implementation can handle
9//! [`Callbacks`](application::Callback) on [`model`](interface::model) data
10//! bound to the `Interface`, and a `Presentation` backend can receive
11//! [`Input`](interface::view::Input) from the user or OS and display a
12//! [`view`](interface::view) of the interface.
13//!
14//! ```
15//! use gooey::{application, presentation, widget, Presentation};
16//! use gooey::interface::{self, Interface, view};
17//! // create a default interface with a headless presentation layer that reads
18//! // from stdin and ignores all display values
19//! let mut interface =
20//!   presentation::Headless::make_interface::<application::Default>();
21//! // attach a widget to the root node
22//! let root_id = interface.root_id().clone();
23//! let action  = interface::Action::create_singleton (
24//!   widget::playback::new (None), interface::CreateOrder::Append);
25//! for event in interface.action (&root_id, action) {
26//!   // ... model events
27//! }
28//! // get stdin and update the interface
29//! for event in interface.update() {
30//!   // ... model events
31//! }
32//! interface.display();  // no-op
33//! ```
34//!
