Expand description

Configuration trait of this pallet.

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

Required Associated Types§

source

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

The overarching event type.

source

type ValidatorId: Member + Parameter + MaybeSerializeDeserialize + MaxEncodedLen + TryFrom<Self::AccountId>

A stable ID for a validator.

source

type ValidatorIdOf: Convert<Self::AccountId, Option<Self::ValidatorId>>

A conversion from account ID to validator ID.

Its cost must be at most one storage read.

source

type ShouldEndSession: ShouldEndSession<Self::BlockNumber>

Indicator for when to end the session.

source

type NextSessionRotation: EstimateNextSessionRotation<Self::BlockNumber>

Something that can predict the next session rotation. This should typically come from the same logical unit that provides ShouldEndSession, yet, it gives a best effort estimate. It is helpful to implement EstimateNextNewSession.
