1//! # Wayland
2//!
3//! **Note:** Windows don't appear on Wayland until you draw/present to them.
4//!
5//! By default, Winit loads system libraries using `dlopen`. This can be
6//! disabled by disabling the `"wayland-dlopen"` cargo feature.
7//!
8//! ## Client-side decorations
9//!
10//! Winit provides client-side decorations by default, but the behaviour can
11//! be controlled with the following feature flags:
12//!
13//! * `wayland-csd-adwaita` (default).
14//! * `wayland-csd-adwaita-crossfont`.
15//! * `wayland-csd-adwaita-notitle`.
