Modules

gridfm

GridFM interchange: a parsed case as the gridfm-datakit Parquet schema.

meta

Per case metadata: matrices emitted, their stats, source file digest, build options. Used by the TUI Inspect screen and as a sidecar for downstream tooling.

mtx

Matrix Market I/O.

Functions

dataset_scenario_ids

The distinct scenario ids of the dataset directory dir in the named from format, ascending, the introspection sibling of read_dataset_dir (and the C ABI’s pio_scenario_ids).

read_dataset_dir

Read one scenario of a dataset directory in the named from format: the directory sibling of powerio::parse_file, and the one place dataset format names are dispatched (the C ABI’s pio_read_dir is a thin wrapper). gridfm is the one dataset format today; scenario selects within it. PyPSA CSV directories are case inputs, not datasets, and parse through parse_file.
