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 configuration trait.

Required Associated Types

type BlockNumber: Parameter + Member + Default + MaybeSerializeDeserialize + MaxEncodedLen

The block number type.

type AccountId: Parameter + Member + MaxEncodedLen

The account type.

type BaseCallFilter: Contains<Self::RuntimeCall>

The basic call filter to use in Origin.

type RuntimeOrigin: Into<Result<RawOrigin<Self::AccountId>, Self::RuntimeOrigin>> + From<RawOrigin<Self::AccountId>>

The runtime origin type.

type RuntimeCall

The runtime call type.

type RuntimeTask

Contains an aggregation of all tasks in this runtime.

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

The runtime event type.

type PalletInfo: PalletInfo

The information about the pallet setup in the runtime.

type DbWeight: Get<RuntimeDbWeight>

The db weights.

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.
