+//! A [`wgpu`] renderer for [`iced_native`].
+//!
+//! ![`iced_wgpu` crate graph](https://github.com/hecrj/iced/blob/cae26cb7bc627f4a5b3bcf1cd023a0c552e8c65e/docs/graphs/wgpu.png?raw=true)
+//!
+//! For now, it is the default renderer of [Iced] in native platforms.
+//!
+//! [`wgpu`] supports most modern graphics backends: Vulkan, Metal, DX11, and
+//! DX12 (OpenGL and WebGL are still WIP). Additionally, it will support the
+//! incoming [WebGPU API].
+//!
+//! Currently, `iced_wgpu` supports the following primitives:
+//! - Text, which is rendered using [`wgpu_glyph`]. No shaping at all.
+//! - Quads or rectangles, with rounded borders and a solid background color.
+//! - Images, lazily loaded from the filesystem.
+//! - Clip areas, useful to implement scrollables or hide overflowing content.
+//!
