Expand description

GRIB data representation and validated packing parameters.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

SimplePacking(ScaledPackingParams)

Template 5.0: Simple packing.

§

Grib1SecondOrderPacking(Grib1SecondOrderPackingParams)

GRIB1 grid-point second-order packing.

GRIB1 stores this layout in Binary Data Section flags rather than a GRIB2 data representation template.

§

ComplexPacking(ComplexPackingParams)

Template 5.2/5.3: Complex packing with optional spatial differencing.

§

IeeePacking(IeeePackingParams)

Template 5.4: IEEE floating-point values.

§

Jpeg2000Packing(Jpeg2000PackingParams)

Template 5.40: JPEG 2000 code stream packing.

§

PngPacking(PngPackingParams)

Template 5.41: PNG image packing.

§

CcsdsPacking(CcsdsPackingParams)

Template 5.42: CCSDS 121.0 adaptive entropy coding.

§

RunLengthPacking(RunLengthPackingParams)

Template 5.200: Run-length packing with predefined level values.

§

Unsupported(u16)

Unsupported template.
