Expand description

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. The module configuration trait.

Required Associated Types§

source

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

The overarching event type.

source

type CollectionId: Member + Parameter + MaxEncodedLen

Identifier for the collection of item.

source

type ItemId: Member + Parameter + MaxEncodedLen + Copy

The type used to identify a unique item within a collection.

source

type Currency: ReservableCurrency<Self::AccountId>

The currency mechanism, used for paying for reserves.

source

type ForceOrigin: EnsureOrigin<Self::RuntimeOrigin>

The origin which may forcibly create or destroy an item or otherwise alter privileged attributes.

source

type CreateOrigin: EnsureOriginWithArg<Self::RuntimeOrigin, Self::CollectionId, Success = Self::AccountId>

Standard collection creation is only allowed if the origin attempting it and the collection are in this set.

source

type Locker: Locker<Self::CollectionId, Self::ItemId>

Locker trait to enable Locking mechanism downstream.

source

type CollectionDeposit: Get<<<Self as Config<I>>::Currency as Currency<<Self as SystemConfig>::AccountId>>::Balance>

The basic amount of funds that must be reserved for collection.

source

type ItemDeposit: Get<<<Self as Config<I>>::Currency as Currency<<Self as SystemConfig>::AccountId>>::Balance>

The basic amount of funds that must be reserved for an item.

source

type MetadataDepositBase: Get<<<Self as Config<I>>::Currency as Currency<<Self as SystemConfig>::AccountId>>::Balance>

The basic amount of funds that must be reserved when adding metadata to your item.

source

type AttributeDepositBase: Get<<<Self as Config<I>>::Currency as Currency<<Self as SystemConfig>::AccountId>>::Balance>

The basic amount of funds that must be reserved when adding an attribute to an item.

source

type DepositPerByte: Get<<<Self as Config<I>>::Currency as Currency<<Self as SystemConfig>::AccountId>>::Balance>

The additional funds that must be reserved for the number of bytes store in metadata, either “normal” metadata or attribute metadata.

source

type StringLimit: Get<u32>

The maximum length of data stored on-chain.

source

type KeyLimit: Get<u32>

The maximum length of an attribute key.

source

type ValueLimit: Get<u32>

The maximum length of an attribute value.

source

type Helper: BenchmarkHelper<Self::CollectionId, Self::ItemId>

A set of helper functions for benchmarking.

source

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.
