Module sparse 

Sparse Arrow/ndarray bridge utilities.

This module defines the custom ndarrow.csr_matrix extension type and zero-copy sparse inbound conversions.

Structs

CsrMatrixBatchExtension

ndarrow.csr_matrix_batch extension type.

CsrMatrixBatchIter

Iterator over per-row sparse matrix views for ndarrow.csr_matrix_batch.

CsrMatrixBatchView

Column-level zero-copy view over ndarrow.csr_matrix_batch storage.

CsrMatrixExtension

ndarrow.csr_matrix extension type.

CsrMatrixMetadata

Metadata carried by ndarrow.csr_matrix.

CsrView

Borrowed CSR view over Arrow buffers.

Functions

csr_batch_to_extension_array

Builds an Arrow StructArray plus extension field for ndarrow.csr_matrix_batch.

csr_matrix_batch_iter

Creates an iterator over per-row zero-copy sparse matrix views for ndarrow.csr_matrix_batch.

csr_matrix_batch_iter_masked

Creates an iterator over per-row zero-copy sparse matrix views for ndarrow.csr_matrix_batch together with the outer validity buffer.

csr_matrix_batch_view

Builds a column-level view over ndarrow.csr_matrix_batch storage.

csr_to_extension_array

Builds an Arrow StructArray plus extension field for ndarrow.csr_matrix.

csr_view_from_columns

Builds a zero-copy CSR view from two Arrow list columns.

csr_view_from_extension

Builds a zero-copy CSR view from a StructArray tagged as ndarrow.csr_matrix.
