§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.

Traits§
- Parachain
Registrar - The parachain registry, as
