Crate vernier_core 

Pure-Rust core for vernier.

This crate has no Python dependencies and is usable directly from Rust binaries, CLI tools, and embedded contexts.

By design, the public API of this crate is the source of truth for vernier’s evaluation semantics. The vernier-ffi crate is a thin data-conversion layer over this one; if you find yourself adding logic to vernier-ffi rather than here, that’s a code smell worth resolving.

See the project’s docs/explanation/ for the architecture overview and docs/adr/ for the design decisions that shaped this crate.

Modules

accumulate

Per-image evaluation → precision/recall/scores arrays.

boundary_parity

Pinned numerical constants for the boundary-IoU subsystem.

breakdown

Generalized Breakdown axis — value-typed slice descriptor that replaces the hardcoded COCO area ranges (ADR-0016, proposed).

dataset

Dataset abstraction and the COCO ground-truth implementation.

distributed

Instance-paradigm body for the partial wire format and merge orchestration (ADR-0031, generalized in ADR-0032).

error

Typed errors for the evaluator.

evaluate

Per-image evaluation orchestrator.

lvis_parity

Pinned numerical constants for the LVIS evaluation subsystem.

matching

Greedy GT × DT matching over a precomputed similarity matrix.

parity

Parity-mode flag and pinned numerical constants.

segmentation

COCO segmentation field deserialization and normalization.

similarity

Similarity computation between ground-truth and detection annotations.

stream

Streaming evaluator (ADR-0013).

summarize

Twelve-stat detection summary atop crate::Accumulated.

tables

Result tables — opt-in DataFrame-shaped views over the locked spine (per ADR-0019).

tide

TIDE error decomposition (Bolya et al., 2020).

Constants

VERSION

Library version string. Useful for parity tracing in fixtures and for debugging mismatches between Rust and Python sides of the FFI boundary.

Functions

dump_bbox_iou_histogram_csv

Stage-0 instrumentation hook for the bbox-IoU optimization plan.
