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. Configuration trait.

Required Associated Types

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

The overarching event type.

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

type RuntimeCall: Parameter + Dispatchable<RuntimeOrigin = Self::RuntimeOrigin, PostInfo = PostDispatchInfo> + GetDispatchInfo + From<Call<Self>>

The overarching call type.

type BlockNumberProvider: BlockNumberProvider

Provider for the block number. Normally this is the frame_system pallet.

type Currency: ReservableCurrency<Self::AccountId>

The currency mechanism.

type ConfigDepositBase: Get<<<Self as Config>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

The base amount of currency needed to reserve for creating a recovery configuration.

This is held for an additional storage item whose value size is 2 + sizeof(BlockNumber, Balance) bytes.

type FriendDepositFactor: Get<<<Self as Config>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

The amount of currency needed per additional user when creating a recovery configuration.

This is held for adding sizeof(AccountId) bytes more into a pre-existing storage value.

type MaxFriends: Get<u32>

The maximum amount of friends allowed in a recovery configuration.

NOTE: The threshold programmed in this Pallet uses u16, so it does not really make sense to have a limit here greater than u16::MAX. But also, that is a lot more than you should probably set this value to anyway…

type RecoveryDeposit: Get<<<Self as Config>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

The base amount of currency needed to reserve for starting a recovery.

This is primarily held for deterring malicious recovery attempts, and should have a value large enough that a bad actor would choose not to place this deposit. It also acts to fund additional storage item whose value size is sizeof(BlockNumber, Balance + T * AccountId) bytes. Where T is a configurable threshold.
