Configuration trait of this pallet.

Implement this type for a runtime in order to customize this pallet.

Required Associated Types§

source

type AuthorityId: Member + Parameter + RuntimeAppPublic + Ord + MaybeSerializeDeserialize + MaxEncodedLen

The identifier type for an authority.

source

type MaxKeys: Get<u32>

The maximum number of keys that can be added.

source

type MaxPeerInHeartbeats: Get<u32>

The maximum number of peers to be stored in ReceivedHeartbeats

source

type MaxPeerDataEncodingSize: Get<u32>

The maximum size of the encoding of PeerId and MultiAddr that are coming from the hearbeat

source

type RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>

The overarching event type.

source

type ValidatorSet: ValidatorSetWithIdentification<Self::AccountId>

A type for retrieving the validators supposed to be online in a session.

source

type NextSessionRotation: EstimateNextSessionRotation<Self::BlockNumber>

A trait that allows us to estimate the current session progress and also the average session length.

This parameter is used to determine the longevity of heartbeat transaction and a rough time when we should start considering sending heartbeats, since the workers avoids sending them at the very beginning of the session, assuming there is a chance the authority will produce a block and they won’t be necessary.
