Crate grib_reader 

Pure-Rust GRIB file reader.

The current implementation supports the production-critical baseline for both GRIB1 and GRIB2: regular latitude/longitude grids, simple packing, and GRIB2 complex packing with general group splitting.

Example

use grib_reader::GribFile;

let file = GribFile::open("gfs.grib2")?;
println!("messages: {}", file.message_count());

for msg in file.messages() {
    println!(
        "  {} {:?} {:04}-{:02}-{:02}T{:02}:{:02}:{:02}Z",
        msg.parameter_name(),
        msg.grid_shape(),
        msg.reference_time().year,
        msg.reference_time().month,
        msg.reference_time().day,
        msg.reference_time().hour,
        msg.reference_time().minute,
        msg.reference_time().second,
    );
}

let data = file.message(0)?.read_data_as_f64()?;
println!("shape: {:?}", data.shape());
