Crate dpp_rules 

dpp-rules — pure EU ESPR cross-field regulatory rules.

Rules are grouped by product group module. Batteries, textiles, and electronics are the active product groups; all others have placeholder modules and will be populated in a later phase.

Inputs are primitive borrowing views so each caller adapts its own representation — typed structs in core, serde_json::Value fields in plugins — without this crate depending on either. That is why this crate is kept separate from dpp-domain: a regulatory rule has exactly one implementation, shared by core and the Wasm plugins alike.

The bundle feature (off by default) adds the ruleset-bundle format + verification seam (the bundle module — conditionally compiled, so not linked here) and pulls in std — see that module’s docs.

Modules

batteries

Batteries — EU Regulation 2023/1542, Annex XIII (battery passport data attributes).

chemicals

Chemical substance rules — REACH, RoHS, EU 2026/405 and related regulations.

common

Cross-product group helper rules: country code validation, unique product identifier syntax, numeric utilities, unit conversions, and the dependency-free date key used for regulatory phase selection.

construction

Construction — regulatory basis pending (ESPR provisional product group).

electronics

Electronics — EU Ecodesign Regulation (ESPR), product group rules. NOTE: repairability scoring (EN 45554 A–E grades, weighted) lives in dpp-calc, not here.

lineage

Lineage rules — the cross-field checks that bind one passport to another.

lint

Passport plausibility lints — non-binding findings that flag implausible data (arithmetic that doesn’t add up, values outside physically plausible ranges, or fields whose declared values are inconsistent with each other), as distinct from the malformed data JSON Schema catches or the non-compliant data a crate::batteries/crate::textiles-style rule catches. A lint finding never blocks publish — see LintSeverity.

metals

Metals — CBAM (EU Regulation 2023/956) and EU ESPR product group rules.

textiles

Textiles — EU ESPR textile product group rules (unsold textiles, garment labelling).

toys

Toys — EN 71 / REACH / ESPR provisional product group.

unsold_goods

Unsold consumer products — the ESPR Art. 25 destruction ban (Annex VII) and the Art. 24 disclosure duty (Impl. Reg. (EU) 2026/2).
