//! # MaaFramework Rust Bindings
//!
//! High-performance, safe Rust bindings for [MaaFramework](https://github.com/MaaXYZ/MaaFramework),
//! a game automation framework based on image recognition.
//!
//! ## Quick Start
//!
//! ```no_run
//! use maa_framework::toolkit::Toolkit;
//! use maa_framework::controller::Controller;
//! use maa_framework::resource::Resource;
//! use maa_framework::tasker::Tasker;
//!
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     // 0. Load library (Dynamic only)
//!     #[cfg(feature = "dynamic")]
//!     maa_framework::load_library(std::path::Path::new("MaaFramework.dll"))?;
//!
//!     // 1. Find devices
//!     let devices = Toolkit::find_adb_devices()?;
//!     let device = devices.first().expect("No device found");
//!
//!     // 2. Create controller
//!     let controller = Controller::new_adb(
//!         device.adb_path.to_str().unwrap(),
//!         &device.address,
//!         "{}",
//!         None,
//!     )?;
//!
//!     // 3. Create resource and tasker
//!     let resource = Resource::new()?;
//!     let tasker = Tasker::new()?;
//!
//!     // 4. Bind and run
//!     tasker.bind(&resource, &controller)?;
//!     let job = tasker.post_task("StartTask", "{}")?;
//!     job.wait();
//!
//!     Ok(())
//! }
//! ```
//!
//! ## Core Modules
//!
//! | Module | Description |
//! |--------|-------------|
//! | [`tasker`] | Task execution and pipeline management |
//! | [`resource`] | Resource loading (images, models, pipelines) |
//! | [`controller`] | Device control (ADB, Win32, PlayCover) |
//! | [`context`] | Task execution context for custom components |
//! | [`toolkit`] | Device discovery utilities |
//! | [`pipeline`] | Pipeline configuration types |
//! | [`job`] | Asynchronous job management |
//! | [`event_sink`] | Event sink system for typed callbacks |
//! | [`buffer`] | Safe data buffers for FFI |
//! | [`custom`] | Custom recognizer and action traits |
//! | [`custom_controller`] | Custom controller implementation |
//! | [`notification`] | Structured event notification parsing |
//! | [`common`] | Common types and data structures |
//! | [`error`] | Error types and handling |
//! | [`util`] | Miscellaneous utility functions |
//! | [`agent_client`] | Remote custom component client |
//! | [`agent_server`] | Remote custom component server |
//!
//! ## Feature Flags
//!
//! - `adb` - ADB controller support (default)
//! - `win32` - Win32 controller support (Windows only)
//! - `custom` - Custom recognizer/action/controller support
//! - `toolkit` - Device discovery utilities
//! - `image` - Integration with the `image` crate
