Usage

To install czv, run:

cargo install czv

Let's say we want to print the total number of rows in a 4x3 CSV file fruits.csv including the header row:

use czv::{RowCount, Result};

fn main() -> Result<()> {
    let data = "\
fruits,price
apple,2.50
banana,3.00
strawberry,1.50
";
    let output = RowCount::new()
        .file_data(data)
        .include_header_row(true)
        .execute()?;
    println!("{output}"); // 4
    Ok(())
}

When ran, this should be the standard output printed in the terminal:

4
