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: broken_files.rs
    path of file: ./repos/czkawka/czkawka_core/src
    
    the code of the file until where you have to start completion: use std::collections::{BTreeMap, HashSet};
use std::fs::File;
use std::io::prelude::*
    
    fn check_broken_pdf(&self, mut file_entry: BrokenEntry) -> Option<BrokenEntry> {
        let parser_options = ParseOptions::tolerant(); // Only show as broken files with really big bugs

        let mut file_entry_clone = file_entry.clone();
        panic::catch_unwind(|| {
            match FileOptions::cached().parse_options(parser_options).open(&file_entry.path) {
                Ok(file) => {
                    for idx in 0..file.num_pages() {
                        if let Err(e) = file.get_page(idx) {
                            let err = validate_pdf_error(&mut file_entry, e);
                            if let PdfError::InvalidPassword = err {
                                return None;
                            }
                            break;
                        }
                    }
                }
                Err(e) => {
                    if let PdfError::Io { .. } = e {
                        return None;
                    }
                    let err = validate_pdf_error(&mut file_entry, e);
                    if let PdfError::InvalidPassword = err {
                        return None;
                    }
                }
            }
            Some(file_entry)
        })
        .unwrap_or_else(|_| {
            let message = create_crash_message("PDF-rs", &file_entry_clone.path.to_string_lossy(), "https://github.com/pdf-rs/pdf");
            println!("{message}");
            file_entry_clone.error_string = message;
            Some(file_entry_clone)
        })
