//! # Joycon-rs Library Documentation
//!
//! Hello, and welcome to joycon-rs documentation.
//!
//! Joycon-rs is a framework for dealing with Nintendo Switch Joy-Con on Rust easily and efficiently.
//! In a way, this library is a wrapper of [`hidapi-rs`].
//! This is a free and open source library, the source code is available for download on [Github].
//!
//! Joycon-rs is in development and is still incomplete.
//! Please be aware that the update will include breaking changes for the time being. Pardon out dust!
//!
//! # Usage
//! First, add dependency to `Cargo.toml`
//!
//! ```toml
//! [dependencies]
//! joycon_rs = "*"
//! ```
//!
//! Then, `use` prelude on `.rs` file.
//! ```
//! use joycon_rs::prelude::*;
//! ```
//!
//! Perfect! Now you have Joycon-rs available in code.
//!
//! ### Receive reports
//! For starters, let's take a simple signal from JoyCon.
//! If you have more than one JoyCon, [`mspc`] can be very helpful.
//!
//! ```no_run
//! use joycon_rs::prelude::*;
//!
//! let (tx, rx) = std::sync::mpsc::channel();
//! let _output = std::thread::spawn( move || {
//!     while let Ok(update) = rx.recv() {
//!         dbg!(update);
//!     }
//! });
//!
//! let manager = JoyConManager::get_instance();
//!
//! let devices = {
//!     let lock = manager.lock();
//!     match lock {
//!         Ok(manager) => manager.new_devices(),
//!         Err(_) => return,
//!     }
//! };
//!
//! devices.iter()
//!     .flat_map(|dev| SimpleJoyConDriver::new(&dev))
//!     .try_for_each::<_, JoyConResult<()>>(|driver| {
//!         // Change JoyCon to Simple hid mode.
//!         let simple_hid_mode = SimpleHIDMode::new(driver)?;
//!
//!         let tx = tx.clone();
//!
//!         // Spawn thread
//!         std::thread::spawn( move || {
//!             loop {
//!                 // Forward the report to the main thread
//!                 tx.send(simple_hid_mode.read_input_report()).unwrap();
//!             }
//!         });
//!
//!         Ok(())
//!     })
//!     .unwrap();
//! ```
//!
//! ### Set player lights
//! Then, lets deal with player lights.
//!
//! ```no_run
//! use joycon_rs::prelude::{*, lights::*};
//! use joycon_rs::joycon::input_report_mode::StandardInputReport;
//! use joycon_rs::joycon::input_report_mode::sub_command_mode::SubCommandReport;
//!
//! let (tx, rx) =
//!     std::sync::mpsc::channel::<JoyConResult<SubCommandReply<StandardInputReport<SubCommandReport<LightsStatus>>>>>();
//!
//! // Receive status of player lights
//! std::thread::spawn(move ||{
//!     while let Ok(Ok(SubCommandReply::Checked(light_status))) = rx.recv() {
//!         assert_eq!(
//!             light_status.extra.reply,
//!             LightsStatus {
//!                 light_up: vec![LightUp::LED1, LightUp::LED3],
//!                 flash: vec![Flash::LED0, Flash::LED2],
//!             }
//!         )
//!     }
//! });
//!
//! let manager = JoyConManager::get_instance();
//!
//! let devices = {
//!     let lock = manager.lock();
//!     match lock {
//!         Ok(manager) => manager.new_devices(),
//!         Err(_) => return,
//!     }
//! };
//!
//! devices.iter()
//!     .flat_map(|dev| SimpleJoyConDriver::new(&dev))
//!     .try_for_each::<_, JoyConResult<()>>(|mut driver| {
//!         // Set player lights
//!         // [SL BUTTON] 📸💡📸💡 [SR BUTTON]
//!         driver.set_player_lights(&vec![LightUp::LED1, LightUp::LED3], &vec![Flash::LED0, Flash::LED2]).unwrap();
//!         tx.send(driver.get_player_lights()).unwrap();
//!         Ok(())
//!     })
//!     .unwrap();
//! ```
//!
//! # Features
//! You can use `Joycon-rs` for...
//! - Manage Joy-Cons
//!    - Connection / Disconnection / Reconnection
//! - [Send] / [Receive] raw packets (u8 array) to / from Joy-Con
//! - [Receive input to Joy-Con][input_report_mode]
//!     - [Receive pushed buttons, and stick directions (one of 8 directions) on every button pressed.][SimpleHIDMode<D>]
//!     - [Receive pushed buttons, stick directions (analog value), and 6-Axis sensor at 60Hz.][StandardFullMode<D>]
//!     - [Get status of Joy-Con][SubCommandMode<D, RD>]
//! - [Deal with LED (Player lights)]
//! - [Vibration (Rumble)]
//!
//! ## Planning
//! - Receive NFC/IR data
//! - Deal with HOME light
