This commit introduces new methods for the `Rect` struct that simplify
the process of splitting a `Rect` into sub-rects according to a given
`Layout`. By putting these methods on the `Rect` struct, we make it a
bit more natural that a layout is applied to the `Rect` itself, rather
than passing a `Rect` to the `Layout` struct to be split.
Adds:
- `Rect::layout` and `Rect::try_layout` methods that allow splitting a
`Rect` into an array of sub-rects according to a given `Layout`.
- `Rect::layout_vec` method that returns a `Vec` of sub-rects.
- `Layout::try_areas` method that returns an array of sub-rects, with
compile-time checks for the number of constraints. This is added
mainly for consistency with the new `Rect` methods.
```rust
use ratatui_core::layout::{Layout, Constraint, Rect};
let area = Rect::new(0, 0, 10, 10);
let layout = Layout::vertical([Constraint::Fill(1); 2]);
// Rect::layout() infers the number of constraints at compile time:
let [top, main] = area.layout(&layout);
// Rect::try_layout() and Layout::try_areas() do the same, but return a
// Result:
let [top, main] = area.try_layout(&layout)?;
let [top, main] = layout.try_areas(area)?;
// Rect::layout_vec() returns a Vec of sub-rects:
let areas_vec = area.layout_vec(&layout);
// you can also explicitly specify the number of constraints:
let areas = area.layout::<2>(&layout);
let areas = area.try_layout::<2>(&layout)?;
let areas = layout.try_areas::<2>(area)?;
```

Ratatui (ˌræ.təˈtu.i) is a Rust crate for cooking up terminal user interfaces (TUIs). It provides a simple and flexible way to create text-based user interfaces in the terminal, which can be used for command-line applications, dashboards, and other interactive console programs.
Quickstart
Ratatui has templates available to help you get started quickly. You can use the
cargo-generate command to create a new project with Ratatui:
cargo install --locked cargo-generate
cargo generate ratatui/templates
Selecting the Hello World template produces the following application:
use color_eyre::Result;
use crossterm::event::{self, Event};
use ratatui::{DefaultTerminal, Frame};
fn main() -> Result<()> {
color_eyre::install()?;
let terminal = ratatui::init();
let result = run(terminal);
ratatui::restore();
result
}
fn run(mut terminal: DefaultTerminal) -> Result<()> {
loop {
terminal.draw(render)?;
if matches!(event::read()?, Event::Key(_)) {
break Ok(());
}
}
}
fn render(frame: &mut Frame) {
frame.render_widget("hello world", frame.area());
}

Acknowledgements
Ratatui was forked from the tui-rs crate in 2023 in order to continue its development. None of this could be possible without Florian Dehau who originally created tui-rs which inspired many Rust TUIs.
Special thanks to Pavel Fomchenkov for his work in designing an awesome logo for the Ratatui project and organization.
