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. Configure the pallet by specifying the parameters and types on which it depends.

Required Associated Types

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

Because this pallet emits events, it depends on the runtime’s definition of an event.

type RuntimeCall: Parameter + Dispatchable<RuntimeOrigin = Self::RuntimeOrigin> + GetDispatchInfo + From<Call<Self>> + IsSubType<Call<Self>> + IsType<<Self as Config>::RuntimeCall>

The overarching call type.

type Currency: ReservableCurrency<Self::AccountId>

The currency mechanism, used for paying for reserves.

type PotId: Member + Parameter + MaxEncodedLen + Copy + From<u32>

Identifier for the pots.

type SponsorshipType: Parameter + Member + Ord + PartialOrd + InstanceFilter<<Self as Config>::RuntimeCall> + MaxEncodedLen + Default

The type for the categories of the calls that could be sponsored. The instance filter determines whether a given call may be sponsored under this type.

IMPORTANT 1: Default must be provided and MUST BE the the most permissive value. IMPORTANT 2: Never sponsor proxy calls or utility calls which allow other calls internally. This would allow a user to bypass the instance filter or alter the origin of the calls.

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

The deposit that must be reserved form the sponsor per their sponsored user.

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

The deposit that must be locked in order to create a pot.

type WeightInfo: WeightInfo

Type representing the weight of this pallet

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
