Reference

Exhaustive technical reference: Python API, Rust API, CLI flags, JSON schemas. Generated where possible; hand-curated where not.

Python API

Generated by mkdocstrings from the public __all__ lists and in-source docstrings — one page per top-level module.

• vernier — top-level utilities (Frequency, ParityMode, COCOeval, version).
• vernier.instance — bbox / segm / boundary / keypoints evaluation.
• vernier.panoptic — panoptic-quality evaluation.
• vernier.semantic — semantic-segmentation evaluation.
• vernier.adapters — drop-in shims (currently the pycocotools COCOeval adapter).

A per-crate Rust API index lands in a follow-up; until then the canonical Rust reference is docs.rs.

Schemas and stat definitions

• vernier eval --emit json output schema — field-by-field shape of the CLI's JSON output.
• COCO 12-stat detection summary — index-by-index definition of summary.stats[0..12].
