//! # Installation
//!
//! ```shell
//! cargo add tui-scrollview
//! ```
//!
//! # Usage
//!
//! ```rust
//! use std::iter;
//!
//! use ratatui::layout::Size;
//! use ratatui::prelude::*;
//! use ratatui::widgets::*;
//! use tui_scrollview::{ScrollView, ScrollViewState};
//!
//! struct MyScrollableWidget;
//!
//! impl StatefulWidget for MyScrollableWidget {
//!     type State = ScrollViewState;
//!
//!     fn render(self, area: Rect, buf: &mut Buffer, state: &mut Self::State) {
//!         // 100 lines of text
//!         let line_numbers = (1..=100).map(|i| format!("{:>3} ", i)).collect::<String>();
//!         let content =
//!             iter::repeat("Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n")
//!                 .take(100)
//!                 .collect::<String>();
//!
//!         let content_size = Size::new(100, 30);
//!         let mut scroll_view = ScrollView::new(content_size);
//!
//!         // the layout doesn't have to be hardcoded like this, this is just an example
//!         scroll_view.render_widget(Paragraph::new(line_numbers), Rect::new(0, 0, 5, 100));
//!         scroll_view.render_widget(Paragraph::new(content), Rect::new(5, 0, 95, 100));
//!
//!         scroll_view.render(buf.area, buf, state);
//!     }
//! }
//! ```
//!
//! # Full Example
//!
//! A full example can be found in the [examples directory].
//! [scrollview.rs]
//!
//! This example shows a scrollable view with two paragraphs of text, one for the line numbers and
//! one for the text. On top of this a Gauge widget is rendered to show that this can be used in
//! combination with any other widget.
//!
