impl<T: Config> Pallet<T>

pub fn next_fee_multiplier() -> Multiplier

Public function to access the next fee multiplier.

pub fn query_info<Extrinsic: ExtrinsicLike + GetDispatchInfo>( unchecked_extrinsic: Extrinsic, len: u32, ) -> RuntimeDispatchInfo<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo>,

Query the data that we know about the fee of a given call.

This pallet is not and cannot be aware of the internals of a signed extension, for example a tip. It only interprets the extrinsic as some encoded value and accounts for its weight and length, the runtime’s extrinsic base weight, and the current fee multiplier.

All dispatchables must be annotated with weight and will have some fee info. This function always returns.

pub fn query_fee_details<Extrinsic: ExtrinsicLike + GetDispatchInfo>( unchecked_extrinsic: Extrinsic, len: u32, ) -> FeeDetails<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo>,

Query the detailed fee of a given call.

pub fn query_call_info( call: T::RuntimeCall, len: u32, ) -> RuntimeDispatchInfo<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo> + GetDispatchInfo,

Query information of a dispatch class, weight, and fee of a given encoded Call.

pub fn query_call_fee_details( call: T::RuntimeCall, len: u32, ) -> FeeDetails<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo> + GetDispatchInfo,

Query fee details of a given encoded Call.

pub fn compute_fee( len: u32, info: &DispatchInfoOf<T::RuntimeCall>, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, ) -> <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance
where T::RuntimeCall: Dispatchable<Info = DispatchInfo>,

Compute the final fee value for a particular transaction.

pub fn compute_fee_details( len: u32, info: &DispatchInfoOf<T::RuntimeCall>, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, ) -> FeeDetails<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo>,

Compute the fee details for a particular transaction.

pub fn compute_actual_fee( len: u32, info: &DispatchInfoOf<T::RuntimeCall>, post_info: &PostDispatchInfoOf<T::RuntimeCall>, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, ) -> <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance
where T::RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>,

Compute the actual post dispatch fee for a particular transaction.

Identical to compute_fee with the only difference that the post dispatch corrected weight is used for the weight fee calculation.

pub fn compute_actual_fee_details( len: u32, info: &DispatchInfoOf<T::RuntimeCall>, post_info: &PostDispatchInfoOf<T::RuntimeCall>, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, ) -> FeeDetails<<<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance>
where T::RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>,

Compute the actual post dispatch fee details for a particular transaction.

pub fn length_to_fee( length: u32, ) -> <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance

Compute the length portion of a fee by invoking the configured LengthToFee impl.

pub fn weight_to_fee( weight: Weight, ) -> <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance

Compute the unadjusted portion of the weight fee by invoking the configured WeightToFee impl. Note that the input weight is capped by the maximum block weight before computation.

pub fn deposit_fee_paid_event( who: T::AccountId, actual_fee: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, tip: <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance, )

Deposit the Event::TransactionFeePaid event.
