Struct SparseTensor 

pub struct SparseTensor {
    pub rows: usize,
    pub cols: usize,
    pub col_ptrs: Vec<usize>,
    pub row_indices: Vec<usize>,
    pub values: Vec<f64>,
    pub integer_data: Option<IntegerStorage>,
}

Fields

rows: usize

cols: usize

col_ptrs: Vec<usize>

Column pointers into row_indices/values; length is cols + 1.

row_indices: Vec<usize>

Zero-based row indices, sorted within each column.

values: Vec<f64>

Floating compatibility view for legacy sparse consumers.

integer_data: Option<IntegerStorage>

Exact homogeneous backing storage for typed integer sparse values.
