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.

sensitivity

Streamed Matrix Market output for DC sensitivity matrices.

Functions

dataset_scenario_ids

Return the distinct scenario IDs in ascending order for dataset directory dir in the named from format. The C ABI exposes the same query through pio_scenario_ids.

read_dataset_dir

Read one scenario from a dataset directory in the named from format. This function dispatches dataset format names; the C ABI’s pio_read_dir wraps it. gridfm is the currently supported dataset format; scenario selects within it. PyPSA CSV directories are case inputs, not datasets, and parse through parse_file.
