use std::io::Write;use std::process::{Command, Stdio};#[derive(Debug)]struct SearchResult {    query: String,    results: Vec<String>,}

4. The function calling the find binary (which does the actual searching) translates the results into the struct from step 1. This is what the function looks like:
