Python binding (pyo3 / maturin)

A thin pyo3 wrapper over the single nirs4all-io Rust core (the facade crate) — all RESOLVE → INFER → CONFIGURE → MATERIALIZE logic lives in Rust; Python only adapts the results.

Layout (mixed maturin)

Native extension nirs4all_io._native (the pyo3 module, built from src/lib.rs).
Python package nirs4all_io (under python/) that wraps _native and adds the lazy SpectroDataset adapter (_adapter.py).

numpy and pandas are wheel runtime dependencies — they back the full-array SpectroDataset reconstruction and are not nirs4all.

Build & install

maturin develop          # build + install into the active venv (dev)
maturin build            # build an abi3 wheel (abi3-py311)
pip install <wheel>      # install the built wheel

Requires Python ≥ 3.11. See PACKAGING.md for the abi3 wheel / nirs4all-formats reuse details.

API

All functions are re-exported from nirs4all_io.

Function	Signature	Returns
`infer`	`infer(input, conventions=None)`	a `DatasetPlan` (data input only)
`to_spec`	`to_spec(input, conventions=None, name=None)`	a `DatasetSpec`
`validate`	`validate(spec)`	`None`; raises `ValueError` if invalid
`load`	`load(input, *, target="assembled", conventions=None, name=None, base_dir=None, spectro_dataset_cls=None)`	summary dict, `DatasetPackage`, or a `SpectroDataset`
`to_dataset_package`	`to_dataset_package(input, *, conventions=None, base_dir=None, name=None)`	a target-agnostic `DatasetPackage`
`describe_dataset_package`	`describe_dataset_package(input, *, conventions=None, base_dir=None, name=None, canonical=False)`	package summary dict or canonical JSON
`to_spectrodataset`	`to_spectrodataset(full, *, spectro_dataset_cls=None)`	a `SpectroDataset`

Inputs (input) accept a str path, a pathlib.Path, a sequence of either (file list), or a dict (a spec). validate additionally accepts a JSON string.

Typed results. infer returns a DatasetPlan and to_spec a DatasetSpec. Both subclass dict — they stay subscriptable, JSON-serializable, and valid inputs to validate / load — and add a readable repr plus convenience accessors:

DatasetSpec: .name, .schema_version, .sources.
DatasetPlan: .overall_score, .resolved_spec (a DatasetSpec), .recommendations, .warnings, and .decisions() (the scored structure/signal_type/task_type decisions, keyed by kind).

>>> plan = nio.infer("/data/run")
>>> plan
DatasetPlan(overall_score=0.883, structure='x_y_separate'(0.85), ...)
>>> plan.decisions().keys()
dict_keys(['structure', 'signal_type', 'task_type'])
>>> plan.resolved_spec
DatasetSpec(name='data', schema_version=1, sources=[data:mixed])

load targets:

target="assembled" → the rounded structural summary dict (no nirs4all).
target="dataset_package" / target="package" → a target-agnostic DatasetPackage with payload manifest hashes and an assembled view.
target="spectrodataset" → a real nirs4all SpectroDataset, built via a lazy nirs4all import inside the adapter. This is the only nirs4all touch-point; import nirs4all_io never imports nirs4all (enforced by tests/test_import_boundary.py). Inject spectro_dataset_cls= to drive the builder with a double (testing without nirs4all).

Usage

from pathlib import Path
import nirs4all_io as nio

plan = nio.infer(Path("/data/run"))            # DatasetPlan (typed dict)
spec = nio.to_spec("/data/run")                # DatasetSpec (typed dict)
nio.validate(spec)                             # raises ValueError if invalid

print(spec.schema_version, len(spec.sources))  # convenience accessors
print(plan.decisions())                        # scored inference decisions

summary = nio.load("/data/run")                # target="assembled" (default)
package = nio.to_dataset_package("/data/run")  # target-agnostic package
ds = nio.load("/data/run", target="spectrodataset")   # nirs4all SpectroDataset
