//! `widgets` is a collection of types that implement [`Widget`] or [`StatefulWidget`] or both.
//!
//! All widgets are implemented using the builder pattern and are consumable objects. They are not
//! meant to be stored but used as *commands* to draw common figures in the UI.
//!
//! The available widgets are:
//! - [`Block`]
//! - [`Tabs`]
//! - [`List`]
//! - [`Table`]
//! - [`Paragraph`]
//! - [`Clear`]
