Configuration trait of this pallet.

The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.

Consequently, a runtime that wants to include this pallet must implement this trait.

Required Associated Types

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

The event type of this module.

type WeightInfo: WeightInfo

Weights for this pallet.

type MaxAuthorities: Get<u32>

Max Authorities in use

type MaxNominators: Get<u32>

The maximum number of nominators for each validator.

type MaxSetIdSessionEntries: Get<u64>

The maximum number of entries to keep in the set id to session index mapping.

Since the SetIdSession map is only used for validating equivocations this value should relate to the bonding duration of whatever staking system is being used (if any). If equivocation handling is not enabled then this value can be zero.

type KeyOwnerProof: Parameter + GetSessionNumber + GetValidatorCount

The proof of key ownership, used for validating equivocation reports The proof include the session index and validator count of the session at which the equivocation occurred.

type EquivocationReportSystem: OffenceReportSystem<Option<Self::AccountId>, (EquivocationProof<Self::Hash, BlockNumberFor<Self>>, Self::KeyOwnerProof)>

The equivocation handling subsystem, defines methods to check/report an offence and for submitting a transaction to report an equivocation (from an offchain context).

Object Safety

This trait is not object safe.
