Trait Config

pub trait Config<I: 'static = ()>: Config + Config<RuntimeEvent: From<Event<Self, I>>> {
    type WeightInfo: WeightInfo;
    type Original: Member + Parameter + MaxEncodedLen;
    type Derivative: Member + Parameter + MaxEncodedLen;
    type DerivativeExtra: Member + Parameter + MaxEncodedLen;
    type CreateOrigin: EnsureOrigin<Self::RuntimeOrigin>;
    type CreateOp: Create<DeriveAndReportId<Self::Original, Option<SaveMappingTo<Self::Derivative>>>>;
    type DestroyOrigin: EnsureOrigin<Self::RuntimeOrigin>;
    type DestroyOp: AssetDefinition<Id = Self::Original> + Destroy<NoParams>;
}

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 WeightInfo: WeightInfo

type Original: Member + Parameter + MaxEncodedLen

The type of an original

type Derivative: Member + Parameter + MaxEncodedLen

The type of a derivative

type DerivativeExtra: Member + Parameter + MaxEncodedLen

Optional derivative extra data

type CreateOrigin: EnsureOrigin<Self::RuntimeOrigin>

An Origin allowed to create a new derivative.

type CreateOp: Create<DeriveAndReportId<Self::Original, Option<SaveMappingTo<Self::Derivative>>>>

Derivative creation operation. Used in the create_derivative extrinsic.

Can be configured to save the mapping between the original and the derivative if it returns Some(SaveMappingTo(DERIVATIVE)).

If the extrinsic isn’t used, this type can be set to DisabledOps.

type DestroyOrigin: EnsureOrigin<Self::RuntimeOrigin>

An Origin allowed to destroy a derivative.

type DestroyOp: AssetDefinition<Id = Self::Original> + Destroy<NoParams>

Derivative destruction operation. Used in the destroy_derivative extrinsic.

If the extrinsic isn’t used, this type can be set to DisabledOps.

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.
