Expand description

Configuration trait of this pallet.

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

Required Associated Types§

The overarching event type.

A stable ID for a validator.

A conversion from account ID to validator ID.

Its cost must be at most one storage read.

Indicator for when to end the session.

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.

Handler for managing new session.

Handler when a session has changed.

The keys.

Weight information for extrinsics in this pallet.
