Struct Column 

pub struct Column {
    pub name: String,
    pub ty: ColType,
    pub cells: Vec<Value>,
}

One named column with an inferred type and its cells in row order.

Fields

name: String

ty: ColType

cells: Vec<Value>

Implementations

impl Column

pub fn new(name: impl Into<String>, cells: Vec<Value>) -> Self

Builds a column from name and cells, inferring ty by folding each cell’s contributed type through ColType::unify.

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

The finite numeric projection of this column (nulls and non-numeric cells dropped). Empty for non-numeric columns — honest absence, not zeros.

pub fn null_count(&self) -> usize

Count of null cells.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
