Implementations

impl DataColumn

pub fn len(&self) -> usize

Number of elements

pub fn is_empty(&self) -> bool

Whether the column is empty

pub fn as_f64(&self) -> Vec<f64>

Convert to f64 values (non-numeric types return empty vec)

pub fn as_strings(&self) -> Vec<String>

Convert to string values

pub fn type_name(&self) -> &'static str

Type name for display

Trait Implementations

impl Clone for DataColumn

fn clone(&self) -> DataColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataColumn

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

Formats the value using the given formatter.
