Struct NativeField 

pub struct NativeField {
    pub dtype: DType,
    pub dims: Vec<String>,
    pub shape: Vec<usize>,
    pub data: ArrayData,
    pub fill_value: Option<f64>,
}

One native-grid array, keyed by its on-disk file_variable name and validated against spec/schemas/native-field.schema.json. The native grid is the loader’s own grid — regrid is ESD/C4’s job, not the reader’s.

Fields

dtype: DType

Logical element type.

dims: Vec<String>

Ordered dimension names (e.g. [time, latitude, longitude]).

shape: Vec<usize>

Length of each dimension, in dims order.

data: ArrayData

Flattened values (row-major per shape).

fill_value: Option<f64>

The native fill sentinel if one survives into the array, else None. CF _FillValue cells are folded into NaN, so a decoded field reports None.

Implementations

impl NativeField

pub fn select_leading(&self, i: usize) -> Result<NativeField>

Slice off the leading dimension at index i, returning the sub-array with one fewer dimension. This is how a crate::Provider selects the current record (time slice) from a multi-record file at a cadence boundary.

Errors if the field is scalar (no leading dim) or i is out of range.

Trait Implementations

impl Clone for NativeField

fn clone(&self) -> NativeField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NativeField

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

Formats the value using the given formatter.
