Fee handler trait.

This should be implemented properly in the runtime to account for native and non-native assets.

Required Associated Types

type Pre

Type returned by pre_dispatch - implementation dependent.

Required Methods

fn pre_dispatch( asset: &FeeAsset, who: &T::AccountId, call: &<T as Config>::RuntimeCall, info: &DispatchInfoOf<<T as Config>::RuntimeCall>, len: usize, ) -> Result<Self::Pre, TransactionValidityError>

Checks if the fee can be paid using the selected asset.

fn post_dispatch( asset: &FeeAsset, pre: Option<Self::Pre>, info: &DispatchInfoOf<<T as Config>::RuntimeCall>, post_info: &PostDispatchInfoOf<<T as Config>::RuntimeCall>, len: usize, result: &DispatchResult, ) -> Result<(), TransactionValidityError>

Charges the call dispatching fee from the multisig directly.

fn handle_creation_fee( imbalance: FeeAssetNegativeImbalance<<T::Currency as Currency<T::AccountId>>::NegativeImbalance, Credit<T::AccountId, T::Tokens>>, )

Charges the fee for creating the core (multisig).
