Crate optic_window 

Windowing and input subsystem for the Optic engine.

Wraps winit (window creation, event loop) and gilrs (gamepad support) into a frame-based input model. Input state is captured once per frame as a snapshot, avoiding callback-driven event handling in game code.

Frame-based input

Every input method accepts an Is action to query:

Action	Meaning
Is::Pressed	True only on the exact frame the button went down
Is::Released	True only on the exact frame the button came up
Is::Held	True every frame while the button is held

This is the same pattern used by frame-based state machines: Pressed is the leading edge, Released is the trailing edge, Held is the level.

Architecture

The Window owns the winit window handle. The Events struct holds per-frame input state (keys, mouse, gamepad). The game loop (optic_loop) drives both: it processes winit events into Events via process_window_event and calls end_frame at the end of each frame.
