Trait TxCreditHold

pub trait TxCreditHold<T: Config> {
    type Credit: FullCodec + DecodeWithMemTracking + MaxEncodedLen + TypeInfo + SuppressedDrop;
}

Needs to be implemented for every OnChargeTransaction.

Cannot be added to OnChargeTransaction directly as this would cause cycles in trait resolution.

Required Associated Types

type Credit: FullCodec + DecodeWithMemTracking + MaxEncodedLen + TypeInfo + SuppressedDrop

The credit that is used to represent the withdrawn transaction fees.

The pallet will put this into a temporary storage item in order to make it available to other pallets during tx application.

Is only used within a transaction. Hence changes to the encoding of this type won’t require a storage migration.

Set to () if your OnChargeTransaction impl does not store the credit.
