Functions

func DecodeStore

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

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

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 RandomizedGenState

func RandomizedGenState(simState *module.SimulationState)

RandomizedGenState generates a random GenesisState for pricefeed

func SimulateMsgUpdatePrices

func SimulateMsgUpdatePrices(ak auth.AccountKeeper, keeper keeper.Keeper, blocks int) simulation.Operation

SimulateMsgUpdatePrices updates the prices of various assets by randomly varying them based on current price

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

Types

type PriceGenerator

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

PriceGenerator allows deterministic price generation in simulations

func NewPriceGenerator

func NewPriceGenerator(startingPrice map[string]sdk.Dec) *PriceGenerator

NewPriceGenerator returns a new market price generator from starting values

func (*PriceGenerator) GetCurrentPrice

func (p *PriceGenerator) GetCurrentPrice(marketID string) sdk.Dec

GetCurrentPrice returns price for last blockHeight set by Step

func (*PriceGenerator) Step

func (p *PriceGenerator) Step(r *rand.Rand, blockHeight int64)

Step walks prices to a current block height from the previously called height noop if called more than once for the same height
