You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: block.rs
    path of file: ./repos/ratatui/src/widgets
    
    the code of the file until where you have to start completion: //! Elements related to the `Block` base widget.
//!
//! This holds everything needed to display and configure a [`Block`].
//!
//! In its simplest form, a `Block` is a [border](Borders) around another widget. It can have a
//! [title](Block::title) and [padding](Block::padding).

use itertools::Itertools;
use strum::{Display, EnumString};

use crate::{prelude::*, symbols::border, widgets::Borders};

mod padding;
pub mod title;

pub use padding::Padding;
    
    fn block_title_style() {
        for alignment in [Alignment::Left, Alignment::Center, Alignment::Right] {
            let mut buffer = Buffer::empty(Rect::new(0, 0, 4, 1));
            Block::default()
                .title("test")
                .title_style(Style::new().yellow())
                .title_alignment(alignment)
                .render(buffer.area, &mut buffer);

            let mut expected_buffer = Buffer::with_lines(vec!["test"]);
            expected_buffer.set_style(Rect::new(0, 0, 4, 1), Style::new().yellow());

            assert_buffer_eq!(buffer, expected_buffer);
        }
