qtrs 0.5.1

//! # qtrs — Rust-style Qt6 bindings
//!
//! A type-safe, builder-pattern-driven Qt6 GUI library for Rust.
//! Built on [`cxx`] for C++ interop, with RAII memory management,
//! signal/callback bridging, and a fluent builder API.
//!
//! ## Installation
//!
//! Add to your `Cargo.toml`:
//!
//! ```toml
//! [dependencies]
//! qtrs = "0.5.1"
//! ```
//!
//! ## Design principles
//!
//! - Builder pattern everywhere — chain `.title("X").size(800, 600).show()`
//! - RAII cleanup — widgets are automatically deleted on `Drop`, with
//!   parent-child awareness (widgets with a Qt parent skip C++ deletion to
//!   avoid double-free).
//! - Type-safe layout ownership — adding a widget to a layout transfers
//!   ownership; the layout drops its children when it goes out of scope.
//! - Zero-cost signal bridging — Qt signals invoke Rust closures via a
//!   single global trampoline; context tokens are plain `u64` values.
//!
//! ## Architecture
//!
//! | Layer | Crate module | What it does |
//! |---|---|---|
//! | C++ glue | *(internal)* | Inline wrappers around Qt5/Qt6 API |
//! | cxx bridge | [`ffi`] | Opaque C++ types + `extern "C++"` signatures |
//! | Safe wrappers | [`app`], [`widget`], [`button`], ... | Builder patterns, RAII, signals |
//! | Public API | *(this module)* | Re-exports of all safe types |
//!

//!         .build();
//!     let label = Label::new("Welcome!").build();
//!
//!     layout.add(btn);
//!     layout.add(label);
//!
//!     window.set_layout(&layout);
//!     window.show();
//!
//!     app.exec();
//! }
//! ```
//!
//! ## Thread safety
//!
//! Qt GUI classes are **not thread-safe**. All widget creation, mutation,
//! and the event loop must happen on the main thread. This library does
//! not add any synchronisation — you are responsible for staying on the
//! right thread, just as in C++ Qt.
//!
//! ## Linking
//!
//! Qt6 (Core, Gui, Widgets) must be installed with development headers.
//! The build script uses `qmake` to locate them. If you see
//! `Qt not found!`, install the `qt6-base-dev` package
//! (or equivalent) for your distribution.
