NumError(ParseIntError { kind: InvalidDigit })

[TonyMistark]

Describe the bug

use std::fs::File;
use std::io::prelude::*;
use docx_rs::*;

fn main() {
    let docx = hello_docx().unwrap();
    println!("{:?}", docx);

}

pub fn hello_docx() -> Result<Docx, ReaderError> {
    // My original docx file generates an error when using read_docx to read it.
    let filename = String::from("docx-rs.docx");
    // The file is named docx-rs.docx, 
    // which was opened with LibreOffice and saved as docx-rs01.docx. 
    // When using read_docx on this modified file, it works fine. 
    // I suspect that there might be some issue with the original file 
    // that prevents it from being read properly. 
    // However, the error message does not provide enough information 
    // for me to pinpoint the exact cause of the problem.
    let filename = String::from("docx-rs01.docx");
    let contents = read_file_contents(&filename).unwrap();
    let docx = docx_rs::read_docx(&contents).unwrap();

    Ok(docx)
}

pub fn read_file_contents(filename: &str) -> Result<Vec<u8>, std::io::Error> {
    let mut contents  = vec![];
    // let mut f = File::open(filename)?;
    let mut f: File = File::open(filename)?;

    let size = f.read_to_end(&mut contents).unwrap();
    println!("size: {}", size);
    Ok(contents)
}

And Then, the error log

Great news!

There is already a pull request that fixes this bug. https://github.com/bokuweb/docx-rs/pull/35 I hope it gets published on crates.io soon.

It's work well:
