Pretty Print HTML In Rust

rust

use std::io::Write;
use std::process::{Command, Stdio};

fn main() {
    let args = vec!["--tidy-mark", "false", "--doctype", "html5"];
    let mut child = Command::new("tidy")
        .args(args)

        .spawn()
        .expect("Failed to spawn child process");
    let mut stdin = child.stdin.take().expect("Failed to open stdin");

        stdin

I haven't found a good crate for pretty printing HTML in rust. There are some, but they are all old and have very few downloads. I don't want to sort through that. For now, I'm shelling out to the [TODO: Code shorthand span ] command line tool like this :

The tidy command is designed to clean up HTML documents. That includes altering them to make fixes when it can. For example, it adds a [TODO: Code shorthand span ] and will reorder nested tags to make them match properly.

I was originally planning to use this to test output from Neopoligen, but that won't work since this can change the code.
