Documentation

pir-types

Shared wire types and tier-layout constants for vote-nullifier-pir — a YPIR-based Private Information Retrieval system that returns non-membership proofs for a ~51M-entry Zcash nullifier set without revealing which nullifier was queried.

This crate contains:

  • Tier-layout constants (PIR_DEPTH, TIER0_LAYERS, TIER1_LAYERS, TIER2_LAYERS, row widths) shared between pir-client, pir-server, and pir-export.
  • Wire types serialized over HTTP: YpirScenario, RootInfo, HealthInfo.
  • Query serialization helper serialize_ypir_query.

Enable the reader feature to get tier-data parsers (tier0::Tier0Data, tier1::Tier1Row, tier2::Tier2Row) and Fp serialization helpers (fp_utils). The default feature set is lightweight and only pulls in serde.

Usage

Pure library; consumed by pir-client and pir-server. Not typically used directly from application code.
