Struct Packing 

pub struct Packing {
    pub scale_factor: f64,
    pub add_offset: f64,
    pub missing: Vec<f64>,
    pub valid_min: Option<f64>,
    pub valid_max: Option<f64>,
}

How a variable’s stored values map to physical ones: Variable::packing. Every bound is in the stored (packed) values’ domain, as the netCDF Users Guide’s attribute conventions ask.

Fields

scale_factor: f64

scale_factor, 1 if absent.

add_offset: f64

add_offset, 0 if absent.

missing: Vec<f64>

Stored values that mean “missing”: the fill value (_FillValue, or the type’s default unless the type is byte) and every missing_value.

valid_min: Option<f64>

The least valid stored value: valid_min, the first of valid_range, or, with neither bound given, just above a fill that is not positive.

valid_max: Option<f64>

The greatest valid stored value: valid_max, the second of valid_range, or, with neither bound given, just below a positive fill.

Implementations

impl Packing

pub fn unpack(&self, stored: f64) -> Option<f64>

The physical value of stored value stored, stored · scale_factor + add_offset, or None if it is missing or outside the valid range.

Trait Implementations

impl Clone for Packing

fn clone(&self) -> Packing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Packing

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Packing

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Packing

fn eq(&self, other: &Packing) -> 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.

impl Serialize for Packing

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
