Struct DataSet 

pub struct DataSet {
    pub columns: Vec<String>,
    pub rows: Vec<DataRow>,
    pub column_types: Vec<DataType>,
}

A dataset of type-safe data

Fields

columns: Vec<String>

Column names (header row)

rows: Vec<DataRow>

Data rows

column_types: Vec<DataType>

Column type metadata

Implementations

impl DataSet

pub fn new() -> Self

Create a new empty dataset

pub fn with_columns(columns: Vec<String>) -> Self

Create a dataset with columns but no data

pub fn push_row(&mut self, row: DataRow)

Add a row to the dataset

pub fn row_count(&self) -> usize

Get the number of rows

pub fn column_count(&self) -> usize

Get the number of columns

pub fn is_empty(&self) -> bool

Check if the dataset is empty

pub fn infer_types(&mut self)

Infer column types from existing data

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 Default for DataSet

fn default() -> Self

Returns the “default value” for a type.

impl From<DataSet> for Vec<Vec<String>>

Conversion to legacy Vec<Vec<String>> format

fn from(dataset: DataSet) -> Vec<Vec<String>>

Converts to this type from the input type.

impl From<Vec<Vec<String>>> for DataSet

Conversion from legacy Vec<Vec<String>> format

fn from(data: Vec<Vec<String>>) -> Self

Converts to this type from the input type.

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.
