pub struct SparseArray(/* private fields */);

Implementations

impl SparseArray

pub fn try_new( indices: ArrayData, values: ArrayData, len: usize, fill_value: Scalar, ) -> VortexResult<Self>

pub fn indices_offset(&self) -> usize

pub fn values(&self) -> ArrayData

pub fn indices(&self) -> ArrayData

pub fn fill_scalar(&self) -> Scalar

pub fn resolved_indices(&self) -> Vec<usize>

Return indices as a vector of usize with the indices_offset applied.

pub fn min_index(&self) -> Option<usize>

Return the minimum index if indices are present.

If this sparse array has no indices (i.e. all elements are equal to fill_value) then it returns None.

pub fn max_index(&self) -> Option<usize>

Return the maximum index if indices are present.

If this sparse array has no indices (i.e. all elements are equal to fill_value) then it returns None.
