#![feature(arc_new_cyclic)]

/*!

Riddle crate dealing with user input (keyboard, mouse, gamepad).

Built largely on the back of `gilrs` and its dependencies for controller support,
and consumes system events from a `riddle-platform` compatible system (`winit`).

The primary functions of this crate is to convert incoming input event streams in
to a queryable immediate-mode-like API, and to unify the incoming event streams in
to a single input event stream.

# Riddle Example

The **recommended** way to use this crate is through the main `riddle` crate.
Riddle exposes this crate through `riddle::input`.

```no_run
use riddle::{*, platform::*, input::*};

fn main() -> Result<(), RiddleError> {
    let rdl =  RiddleLib::new()?;
    let window = WindowBuilder::new().build(rdl.context())?;

    rdl.run(move |rdl| {
        match rdl.event() {
            Event::Input(InputEvent::KeyDown { .. }) => rdl.quit(),
            _ => (),
        }
    })
}
```

# Direct Example

If you don't want to depend on `riddle`, you can use this crate directly. In order to have
the crate function, appropriate `riddle_platform_common::PlatformEvent`s must be sent
to the input system via the `EventPub` it is constructed with.

```no_run
use riddle_input::*;
use riddle_common::eventpub::*;
use riddle_platform_common::*;

fn main() -> Result<(), InputError> {
    let platform_events: EventPub<PlatformEvent> = EventPub::new();
    let (input_system, mut main_thread_state) = InputSystem::new(&platform_events)?;

    platform_events.dispatch(PlatformEvent::MouseButtonDown{
        window: WindowId::new(0),
        button: MouseButton::Left});

    main_thread_state.process_input();

    let input_events: Vec<InputEvent> = input_system.take_input_events();

    Ok(())
}
```
