Implementations

impl DeviceCsrMatrix

pub fn new( rows: usize, cols: usize, rowptr: DeviceBuffer<i32>, colidx: DeviceBuffer<i32>, values: DeviceBuffer<f64>, ) -> Self

Construct a CSR matrix, enforcing the structural invariant that rowptr holds exactly rows + 1 entries.

A CSR row-pointer array must have one slot per row plus a trailing slot equal to nnz. If the supplied rowptr violates this (too short or too long), it is canonicalized to rows + 1 monotone entries: a short rowptr is padded with its final value (marking the remaining rows as empty) and an over-long rowptr is truncated. This prevents downstream row-slice and deallocation paths from indexing rowptr[row + 1] out of bounds, which would be an invalid-free / out-of-bounds deallocation hazard.

pub const fn nnz(&self) -> usize
