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 Fungibles: FungiblesMutate<Self::AccountId, AssetId = Self::AssetId> + FungiblesMetadataInspect<Self::AccountId> + FungiblesRolesInspect<Self::AccountId>

Fungibles implementation for both internal and external assets.

type Consideration: Consideration<Self::AccountId, Footprint>

Consideration for PSM creation. Runtimes can price this from the PSM footprint or anything else they choose.

type CreateOrigin: EnsureOriginWithArg<<Self as Config>::RuntimeOrigin, Self::AssetId, Success = Option<Self::AccountId>>

Origin permitted to create a PSM for a given internal asset; succeeds with the optional account that pays the creation consideration. Returning None creates without a deposit, useful for privileged origins such as Root.

type RuntimeOrigin: OriginTrait<PalletsOrigin = Self::PalletsOrigin> + From<Self::PalletsOrigin> + IsType<<Self as Config>::RuntimeOrigin>

The aggregated origin, tying the runtime origin to Config::PalletsOrigin so PSM admins can be matched against incoming origins.

type PalletsOrigin: Parameter + From<RawOrigin<Self::AccountId>> + CallerTrait<Self::AccountId> + MaxEncodedLen

The caller origin, overarching type of all pallets’ origins. Stored as a PSM’s full_admin / emergency_admin and matched against incoming origins.

type AssetId: Parameter + Member + Clone + MaybeSerializeDeserialize + MaxEncodedLen + Ord

Asset identifier type.

type WeightInfo: WeightInfo

A type representing the weights required by the dispatchables of this pallet.

type PalletId: Get<PalletId>

PalletId for deriving each PSM instance’s reserve sub-account.

type MaxExternals: Get<u32>

Maximum number of approved external assets per PSM instance.

type BenchmarkHelper: BenchmarkHelper<Self::AssetId, Self::AccountId>

Helper for benchmarks to create an external asset with correct metadata.

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.
