Crate pallet_staking_async_ah_client

The client for AssetHub, intended to be used in the relay chain.

The counter-part for this pallet is pallet-staking-async-rc-client on AssetHub.

This documentation is divided into the following sections:

1. Incoming messages: the messages that we receive from the relay chian.
2. Outgoing messages: the messaged that we sent to the relay chain.
3. Local interfaces: the interfaces that we expose to other pallets in the runtime.

Incoming Messages

All incoming messages are handled via Call. They are all gated to be dispatched only by Config::AssetHubOrigin. The only one is:

• Call::validator_set: A new validator set for a planning session index.

Outgoing Messages

All outgoing messages are handled by a single trait SendToAssetHub. They match the incoming messages of the ah-client pallet.

Local Interfaces:

Living on the relay chain, this pallet must:

• Implement [pallet_session::SessionManager] (and historical variant thereof) to give information to the session pallet.
• Implements SessionInterface to receive information from the session pallet
• Implement [sp_staking::offence::OnOffenceHandler].
• Implement reward related APIs ([frame_support::traits::RewardsReporter]).

Future Plans

• Governance functions to force set validators.

DefaultExposureOf

See pallet_staking::DefaultExposureOf. This type is the same, except it is duplicated here so that an rc-runtime can use it after pallet-staking is fully removed as a dependency.

Enums

OperatingMode

Represents the operating mode of the pallet.

Traits

The interface to communicate to asset hub.

SessionInterface

Interface to talk to the local session pallet.
