Format defaults

The default Excel cell format is a font setting of Calibri size 11 with all other properties turned off.

It is occasionally useful to use a default format with a method that requires a format but where you don't actually want to change the formatting.

//! The following example demonstrates creating a default format.

use rust_xlsxwriter::{Format, Workbook, XlsxError};

fn main() -> Result<(), XlsxError> {
    // Create a new Excel file object.
    let mut workbook = Workbook::new();

    // Add a worksheet.
    let worksheet = workbook.add_worksheet();

    // Create a new default format.
    let format = Format::default();

    // These methods calls are equivalent.
    worksheet.write_string(0, 0, "Hello")?;
    worksheet.write_string_with_format(1, 0, "Hello", &format)?;

    workbook.save("formats.xlsx")?;

    Ok(())
}

Output showing that both strings have the same format:
