windows and lets you handle events (for example: the window being
resized, a key being pressed, a mouse movement, etc.) produced by
window.

Winit is designed to be a low-level brick in a hierarchy of libraries.
Consequently, in order to show something on the window you need to use
the platform-specific getters provided by winit, or another library.")
