lookbook.manifest

Helpers for reading and writing the manifest.

The manifest is a MutableMapping[(image_id, metric_id), Annotation]. This module is a tiny ergonomics layer on top — nothing here is essential to the abstraction; it exists so callers don’t have to spell out tuple keys.

lookbook.manifest.get_annotation(manifest: MutableMapping[Tuple[str, str], Annotation], image_id: str, metric_id: str) → Annotation | None

Return the annotation if present, else None.

lookbook.manifest.image_ids(manifest: MutableMapping[Tuple[str, str], Annotation]) → Iterable[str]

The set of distinct image_ids that appear in the manifest.

lookbook.manifest.iter_annotations_for(manifest: MutableMapping[Tuple[str, str], Annotation], image_id: str) → Iterator[Annotation]

Yield every annotation for a given image.

lookbook.manifest.put_annotation(manifest: MutableMapping[Tuple[str, str], Annotation], annotation: Annotation) → None

Write an annotation to the manifest, keyed by (image_id, metric_id).

lookbook.manifest.value_of(manifest: MutableMapping[Tuple[str, str], Annotation], image_id: str, metric_id: str, default: Any = None) → Any

Return the bare value of an annotation (not the wrapper), or default.
