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: wrap_map.rs
    path of file: ./repos/zed/crates/editor/src/display_map
    
    the code of the file until where you have to start completion: use super::{
    fold_map::FoldBufferRows,
    tab_map::{self, TabEdit, TabPoint, TabSnapshot},
    Highlights,
};
use gpui::{AppContext, Context, Font, LineWrapper, Model, ModelContext, Pixels, Task};
use language::{Chunk, Point};
use lazy_static::lazy_static;
use multi_buffer::MultiBufferSnapshot;
use smol::future::yield_now;
use std::{cmp
    
        fn verify_chunks(&mut self, rng: &mut impl Rng) {
            for _ in 0..5 {
                let mut end_row = rng.gen_range(0..=self.max_point().row());
                let start_row = rng.gen_range(0..=end_row);
                end_row += 1;

                let mut expected_text = self.text_chunks(start_row).collect::<String>();
                if expected_text.ends_with('\n') {
                    expected_text.push('\n');
                }
                let mut expected_text = expected_text
                    .lines()
                    .take((end_row - start_row) as usize)
                    .collect::<Vec<_>>()
                    .join("\n");
                if end_row <= self.max_point().row() {
                    expected_text.push('\n');
                }

                let actual_text = self
                    .chunks(start_row..end_row, true, Highlights::default())
                    .map(|c| c.text)
                    .collect::<String>();
                assert_eq!(
                    expected_text,
                    actual_text,
                    "chunks != highlighted_chunks for rows {:?}",
                    start_row..end_row
                );
            }
        }
