Functions

func CombinedFeeRequirement

func CombinedFeeRequirement(globalFees, minGasPrices sdk.Coins) (sdk.Coins, error)

CombinedFeeRequirement returns the global fee and min_gas_price combined and sorted. Both globalFees and minGasPrices must be valid, but CombinedFeeRequirement does not validate them, so it may return 0denom. if globalfee is empty, CombinedFeeRequirement return sdk.Coins{}

func ContainZeroCoins

func ContainZeroCoins(coins sdk.Coins) bool

ContainZeroCoins returns true if the given coins are empty or contain zero coins, Note that the coins denoms must be validated, see sdk.ValidateDenom

func Find

func Find(coins sdk.Coins, denom string) (bool, sdk.Coin)

Find replaces the functionality of Coins.Find from SDK v0.46.x

func GetMinGasPrice

func GetMinGasPrice(ctx sdk.Context, gasLimit int64) sdk.Coins

GetMinGasPrice returns a nodes's local minimum gas prices fees given a gas limit

Types

type FeeDecorator

type FeeDecorator struct {
	GlobalMinFeeParamSource globalfee.ParamSource
	StakingKeeper           *stakingkeeper.Keeper
}

func NewFeeDecorator

func NewFeeDecorator(globalfeeSubspace paramtypes.Subspace, sk *stakingkeeper.Keeper) FeeDecorator

func (FeeDecorator) AnteHandle

func (mfd FeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)

AnteHandle implements the AnteDecorator interface

func (FeeDecorator) ContainsOnlyBypassMinFeeMsgs

func (mfd FeeDecorator) ContainsOnlyBypassMinFeeMsgs(ctx sdk.Context, msgs []sdk.Msg) bool

func (FeeDecorator) DefaultZeroGlobalFee

func (mfd FeeDecorator) DefaultZeroGlobalFee(ctx sdk.Context) ([]sdk.DecCoin, error)

DefaultZeroGlobalFee returns a zero coin with the staking module bond denom

func (FeeDecorator) GetBypassMsgTypes

func (mfd FeeDecorator) GetBypassMsgTypes(ctx sdk.Context) (res []string)

func (FeeDecorator) GetGlobalFee

func (mfd FeeDecorator) GetGlobalFee(ctx sdk.Context, feeTx sdk.FeeTx) (sdk.Coins, error)

GetGlobalFee returns the global fees for a given fee tx's gas (might also return 0denom if globalMinGasPrice is 0) sorted in ascending order. Note that ParamStoreKeyMinGasPrices type requires coins sorted.

func (FeeDecorator) GetMaxTotalBypassMinFeeMsgGasUsage

func (mfd FeeDecorator) GetMaxTotalBypassMinFeeMsgGasUsage(ctx sdk.Context) (res uint64)

func (FeeDecorator) GetTxFeeRequired

func (mfd FeeDecorator) GetTxFeeRequired(ctx sdk.Context, tx sdk.FeeTx) (sdk.Coins, error)

GetTxFeeRequired returns the required fees for the given FeeTx. In case the FeeTx's mode is CheckTx, it returns the combined requirements of local min gas prices and global fees. Otherwise, in DeliverTx, it returns the global fee.
