type InfiniteGasMeter 

type InfiniteGasMeter struct {
	// contains filtered or unexported fields
}

InfiniteGasMeter: A special impl of `sdk.GasMeter` that ignores any gas limits, allowing an unlimited amount of gas to be consumed. This is especially useful for scenarios where gas consumption needs to be monitored but not restricted, such as during testing or in parts of the chain where constraints are meant to be set differently.

func (*InfiniteGasMeter) ConsumeGas
