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: markdown.rs
    path of file: ./repos/rustup/src/cli
    
    the code of the file until where you have to start completion: // Write Markdown to the terminal
use std::io::Write;

use pulldown_cmark::{Event, Tag, TagEnd};

use crate::currentprocess::terminalsource::{Attr, Color, ColorableTerminal};

// Handles the wrapping of text written to the console
struct LineWrapper<'a> {
    indent: u32,
    margin: u32,
    pos: u32,
    w: &'a mut ColorableTerminal,
}

impl<'a> LineWrapper<'a> {
    // Just write a newline
    fn write_line(&mut self) {
        let _ = writeln!(self.w.lock());
        // Reset column position to start of line
        self.pos = 0;
    }
    // Called before writing text to ensure indent is applied
    fn write_indent(&mut self) {
        if self.pos == 0 {
            // Write a space for each level of indent
            for _ in 0..self.indent {
                let _ = write!(self.w.lock(), " ");
            }
            self.pos = self.indent;
        }
    }
    // Write a non-breaking word
    fn w
