Feature: Manually add headers to new CSV, using proposed csv::Writer.push_header() function

Oh duh. I was mentally separating the concept of a record and a header, without thinking about the fact that I could do what you just said. 😅

I don't understand the request. You can write a header record just like you would any other record. Why not try that?

fn main() -> Result<(), csv::Error> {
    let mut writer = csv::Writer::from_writer(std::io::stdout());

    let mut new_record = csv::StringRecord::new();
    new_record.push_field("first_name");
    new_record.push_field("last_name");
    writer.write_record(&new_record)?;
  
    let mut new_record = csv::StringRecord::new();
    new_record.push_field("Trevor");
    new_record.push_field("Sullivan");
    writer.write_record(&new_record)?;
  
    Ok(())
}
