Struct Float64Column 

pub struct Float64Column {
    pub id: VariableId,
    pub values: F64Buffer,
    pub validity: ValidityBitmap,
}

Float64 column (owned or foreign-backed values).

Fields

id: VariableId

Variable id.

values: F64Buffer

Values (sentinel-free; use validity for missing).

validity: ValidityBitmap

Validity bitmap.

Implementations

impl Float64Column

pub fn new( id: VariableId, values: impl Into<F64Buffer>, validity: ValidityBitmap, ) -> Result<Self, DataError>

Construct a column from owned values; lengths must match.

Errors

DataError::LengthMismatch when validity length differs.

pub fn len(&self) -> usize

Row count.

pub fn is_empty(&self) -> bool

Whether empty.

pub fn as_f64_view(&self) -> F64VectorView<'_>

Borrowed contiguous view (no allocation).
