Crate registrar_primitives 

Parachain-registrar shared primitives

Types shared by the parachain registrar pallet (pallet-registrar-para) and relay-chain registrar pallet (pallet-registrar-relay). This crate is deliberately free of any FRAME, XCM, or network-specific dependency, so a single version of the wire types serves Westend, Kusama and Polkadot, and so both pallets can depend on it without forming a dependency cycle.

For the same reason the types here are plain: a para id is a u32 (byte-compatible with the relay chain’s Id newtype), head data and validation code are Vec<u8>, and a validation code hash is an [H256] (what ValidationCodeHash wraps). The same holds for ParachainRegistrar, the interface the relay pallet drives the registry through: conversion to the relay chain’s own types happens in the pallet implementing it.
