Enum Column 

pub enum Column {
    Int(Vec<i64>),
    Float(Vec<f64>),
    Str(Vec<String>),
    Bool(Vec<bool>),
}

A single typed column of data.

Variants

Int(Vec<i64>)

64-bit signed integer column.

Float(Vec<f64>)

64-bit floating-point column.

Str(Vec<String>)

UTF-8 string column.

Bool(Vec<bool>)

Boolean column.

Implementations

impl Column

pub fn len(&self) -> usize

Number of rows.

pub fn is_empty(&self) -> bool

Whether the column is empty.

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

Human-readable type name.

pub fn get_display(&self, idx: usize) -> String

Get a display-friendly string value at index.

pub fn get_f64(&self, idx: usize) -> Option<f64>

Get value as f64 (for numeric aggregation). Returns None for non-numeric.

pub fn compare_rows(&self, a: usize, b: usize) -> Ordering

Compare two rows within this column. Used by sort.

pub fn gather(&self, indices: &[usize]) -> Column

Gather rows by index — create a new column from selected rows.

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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