Examples

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let f = std::fs::File::open(
        "testdata/icon_global_icosahedral_single-level_2021112018_000_TOT_PREC.grib2",
    )?;
    let f = std::io::BufReader::new(f);
    let result = grib::from_reader(f);

    assert!(result.is_ok());
    let grib2 = result?;
    assert_eq!(grib2.len(), 1);
    Ok(())
