Struct FixedVectorColumn 

pub struct FixedVectorColumn {
    pub id: VariableId,
    pub dim: usize,
    pub values: Arc<[f64]>,
    pub validity: ValidityBitmap,
}

Owned fixed-size vector column (row-major: values[row * dim + component]).

Fields

id: VariableId

Variable id.

dim: usize

Vector dimensionality.

values: Arc<[f64]>

Flattened values.

validity: ValidityBitmap

Per-row validity.

Implementations

impl FixedVectorColumn

pub fn new( id: VariableId, dim: usize, values: impl Into<Arc<[f64]>>, validity: ValidityBitmap, ) -> Result<Self, DataError>

Construct a fixed-vector column.

Errors

Length / shape mismatch.

pub fn len(&self) -> usize

Row count.

pub fn is_empty(&self) -> bool

Whether empty.
