Functions

func DecodeStore

func DecodeStore(cdc *codec.Codec, kvA, kvB kv.Pair) string

DecodeStore unmarshals the KVPair's Value to the corresponding auction type

func GenBidDuration

func GenBidDuration(r *rand.Rand) time.Duration

func GenIncrementCollateral

func GenIncrementCollateral(r *rand.Rand) sdk.Dec

func GenMaxAuctionDuration

func GenMaxAuctionDuration(r *rand.Rand) time.Duration

func ParamChanges

func ParamChanges(r *rand.Rand) []simulation.ParamChange

ParamChanges defines the parameters that can be modified by param change proposals on the simulation

func RandInt

func RandInt(r *rand.Rand, inclusiveMin, exclusiveMax sdk.Int) (sdk.Int, error)

RandInt randomly generates an sdk.Int in the range [inclusiveMin, exclusiveMax). It works for negative and positive integers.

func RandIntInclusive

func RandIntInclusive(r *rand.Rand, inclusiveMin, inclusiveMax sdk.Int) (sdk.Int, error)

RandIntInclusive randomly generates an sdk.Int in the range [inclusiveMin, inclusiveMax]. It works for negative and positive integers.

func RandomPositiveDuration

func RandomPositiveDuration(r *rand.Rand, inclusiveMin, exclusiveMax time.Duration) (time.Duration, error)

func RandomizedGenState

func RandomizedGenState(simState *module.SimulationState)

RandomizedGenState generates a random GenesisState for auction

func SimulateMsgPlaceBid

func SimulateMsgPlaceBid(ak auth.AccountKeeper, keeper keeper.Keeper) simulation.Operation

SimulateMsgPlaceBid returns a function that runs a random state change on the module keeper. There's two error paths - return a OpMessage, but nil error - this will log a message but keep running the simulation - return an error - this will stop the simulation

func WeightedOperations

func WeightedOperations(
	appParams simulation.AppParams, cdc *codec.Codec, ak auth.AccountKeeper, k keeper.Keeper,
) simulation.WeightedOperations

WeightedOperations returns all the operations from the module with their respective weights
