Module index_ops 

Index operations (replacement, set operations, contraction preparation).

Structs

ContractionSpec

Result of preparing a tensor contraction.

Enums

ContractionError

Error type for contraction preparation.

ReplaceIndsError

Error type for index replacement operations.

Functions

check_unique_indices

Check if a collection of indices contains any duplicates (by ID).

common_ind_positions

Find contractable indices between two slices and return their positions.

common_inds

Find common indices between two index collections.

hascommoninds

Check if two collections have any common indices (by ID).

hasind

Check if a collection contains a specific index (by ID).

hasinds

Check if a collection contains all of the specified indices (by ID).

noncommon_inds

Find indices that are not common between two collections (symmetric difference).

prepare_contraction

Prepare contraction data for two tensors that share common indices.

prepare_contraction_pairs

Prepare contraction data for explicit index pairs (like tensordot).

replaceinds

Replace indices in a collection based on ID matching.

replaceinds_in_place

Replace indices in-place based on ID matching.

union_inds

Find the union of two index collections.

unique_inds

Find indices that are unique to the first collection (set difference A \ B).
