## Usage

To install `czv`, run:

```bash
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:

```rust
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:

```console
4
```

## Tests
