gpui-kit 0.6.6

//! GPUI Kit: one dependency for building desktop applications with GPUI.
//!
//! GPUI itself is published as a family of `gpui-pre-*` crates that move
//! together. This crate depends on the matching set for you, so an
//! application lists `gpui-kit` alone. `use gpui_kit::*;` is GPUI, and each
//! layer is reachable by name:
//!
//! | Path            | Crate             | Feature          |
//! | --------------- | ----------------- | ---------------- |
//! | `gpui_kit::*`   | `gpui`            | always           |
//! | `platform`      | `gpui_platform`   | desktop / web    |
//! | [`base`]        | `gpui-base`       | always           |
//! | [`component`]   | `gpui-component`  | `component` (on) |
//! | [`assets`]      | `gpui-kit-assets` | `assets` (on)    |
//!
//! On desktop and web, `application` opens the platform. Mobile applications
//! supply their backend to `Application::with_platform`. [`init`] initializes the enabled
//! layers:
//!
//! ```no_run
//! use gpui_kit::*;
//!
//! actions!(hello, [Quit]);
//!
//! struct Hello;
//!
//! impl Render for Hello {
//!     fn render(&mut self, _: &mut Window, _: &mut Context<Self>) -> impl IntoElement {
//!         div().child("Hello, World!")
//!     }
//! }
//!
//! fn main() {
//!     gpui_kit::application().run(|cx| {
//!         gpui_kit::init(cx);
//!         cx.spawn(async move |cx| {
//!             cx.open_window(WindowOptions::default(), |_, cx| cx.new(|_| Hello))
//!                 .expect("failed to open window");
//!         })
//!         .detach();
//!     });
//! }
//! ```
//!
//! See [`component`] for the same program with the styled component library.

// Public facade decision — 2026-09-08:
// GPUI Kit is the application-facing entry point. Users should depend on and
// import gpui-kit without needing to know which GPUI crates implement it.
// Keep GPUI APIs available through the Kit root and preserve the published
// #[gpui_kit::test] macro. Do not replace it with Rust's built-in #[test].
// A future switch to official GPUI crates is an internal dependency migration,
// not a reason to steer Kit users toward gpui:: paths or require import changes.
// Keep the existing gpui namespace re-export hidden for source compatibility;
// it is not the recommended application API.
//
// With test-support, the glob below includes GPUI's test macro. Test modules
// should import their Kit types explicitly to avoid shadowing Rust's #[test].
