Enum ColumnVector 

pub enum ColumnVector {
    Int64 {
        data: Vec<i64>,
        validity: Option<Vec<bool>>,
    },
    Float64 {
        data: Vec<f64>,
        validity: Option<Vec<bool>>,
    },
    Bool {
        data: Vec<bool>,
        validity: Option<Vec<bool>>,
    },
    Text {
        data: Vec<String>,
        validity: Option<Vec<bool>>,
    },
}

Typed column storage. Nullable columns carry the validity bits alongside the payload so Option isn’t materialised row-by-row.
