//! Carnelian is a prototype framework for writing
//! [Fuchsia](https://fuchsia.dev/fuchsia-src/concepts)
//! applications in
//! [Rust](https://www.rust-lang.org/).
//!
//! Below is a tiny example of a Carnelian app.
//!
//! The [`ViewAssistant`] trait is a good place to start when learning
//! about Carnelian.
//!
//! ```no_run

//! use carnelian::{
//!     make_app_assistant,
//!     render::{self},
//!     App, AppAssistant, ViewAssistant, ViewAssistantContext, ViewAssistantPtr, ViewKey,
//! };
//! use fuchsia_zircon::Event;
//!
//! #[derive(Default)]
//! struct SampleAppAssistant;
//!
//! impl AppAssistant for SampleAppAssistant {
//!     fn setup(&mut self) -> Result<(), Error> {
//!         Ok(())
//!     }
//!
//!     fn create_view_assistant(&mut self, _: ViewKey) -> Result<ViewAssistantPtr, Error> {
//!         SampleViewAssistant::new()

//! struct SampleViewAssistant;

//! impl SampleViewAssistant {
//!     fn new() -> Result<ViewAssistantPtr, Error> {
