Trait Config

pub trait Config: Config<RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo, RuntimeOrigin = <Self as Config>::RuntimeOrigin>, RuntimeOrigin: AsTransactionAuthorizedOrigin + From<RawOrigin<Self::AccountId>>> {
    type WeightInfo: WeightInfo;
    type RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>;
    type Extension: TransactionExtension<<Self as Config>::RuntimeCall>;
}

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

Weight information for calls in this pallet.

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

The overarching event type.

type Extension: TransactionExtension<<Self as Config>::RuntimeCall>

Transaction extension/s for meta transactions.

The extensions that must be present in every meta transaction. This generally includes extensions like pallet_verify_signature::VerifySignature, [frame_system::CheckSpecVersion], [frame_system::CheckTxVersion], [frame_system::CheckGenesis], [frame_system::CheckMortality], [frame_system::CheckNonce], etc. Check the mock setup for the example.

The types implementing the [TransactionExtension] trait can be composed into a tuple type that will implement the same trait by piping invocations through each type.

In the runtime-benchmarks environment the type must implement Default trait. The extension must provide an origin and the extension’s weight must be zero. Use pallet_meta_tx::WeightlessExtension type when the runtime-benchmarks feature enabled.

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.
