Notes

• The unpacked subset is a set of values defined in the same way as the full set of values (on a spectrum limited to j_s, k_s and m_s ), but on which scaling and packing are not applied. Associated values are stored in octets 6 onwards of section 7.
• The remaining coefficients are multiplied by (n x (n+1))p , scaled and packed. The operator associated with this multiplication is derived from the Laplacian operator on the sphere.
• The retrieval formula for a coefficient of wave number n is then: Y = (R+X x 2e ) x 10-d x (n x(n+1))-p where X is the packed scaled value associated with the coefficient.

Description of how to decode simple unpacked data

Fields

reference_value: f32

Reference value (R) (IEEE 32-bit floating-point value)

binary_scale_factor: i32

Binary scale factor (E)

decimal_scale_factor: i32

Decimal scale factor (D)

number_of_bits: u8

Number of bits used for each packed value for simple packing, or for each group reference value for complex packing or spatial differencing

Implementations

impl Grib2Template551

pub fn new<T: Reader>(section: &T) -> Self

Create a new instance of Grib2Template540

Trait Implementations

impl Clone for Grib2Template551

fn clone(&self) -> Grib2Template551

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Grib2Template551

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Grib2Template551

fn eq(&self, other: &Grib2Template551) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
