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 pallet configuration trait

Required Associated Types§

source

type Moment: Parameter + Default + AtLeast32Bit + Scale<BlockNumberFor<Self>, Output = Self::Moment> + Copy + MaxEncodedLen + StaticTypeInfo

Type used for expressing a timestamp.

source

type OnTimestampSet: OnTimestampSet<Self::Moment>

Something which can be notified (e.g. another pallet) when the timestamp is set.

This can be set to () if it is not needed.

source

type MinimumPeriod: Get<Self::Moment>

The minimum period between blocks.

Be aware that this is different to the expected period that the block production apparatus provides. Your chosen consensus system will generally work with this to determine a sensible block time. For example, in the Aura pallet it will be double this period on default settings.

source

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

Object Safety§

This trait is not object safe.
