Struct DataSet 

pub struct DataSet { /* private fields */ }

A column-oriented table value (the DataSet datatype).

Construct via DataSet::new, which validates that columns, types, and every row share the same width (tck-id-payloads-dataset-*).

Implementations

impl DataSet

pub fn new( columns: Vec<String>, types: Vec<DataType>, rows: Vec<Vec<DataSetValue>>, ) -> Result<Self>

Build and validate a DataSet.

Errors

Returns SparkplugError::DataSetShape if columns.len() != types.len(), any column type is not a basic scalar, or any row’s width differs from the column count.

pub fn num_of_columns(&self) -> u64

The number of columns (num_of_columns on the wire).

pub fn columns(&self) -> &[String]

The column names.

pub fn types(&self) -> &[DataType]

The per-column datatypes.

pub fn rows(&self) -> &[Vec<DataSetValue>]

The rows (each row has one DataSetValue per column).

Trait Implementations

impl Clone for DataSet

fn clone(&self) -> DataSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataSet

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

Formats the value using the given formatter.

impl PartialEq for DataSet

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