func InitGenesis(ctx sdk.Context, keeper Keeper, data GenesisState)

new oracle genesis

func NewHandler 

func NewHandler(k Keeper) sdk.Handler

NewHandler creates a new handler for all market type messages.

func NewQuerier added in v0.2.0 

func NewQuerier(keeper Keeper) sdk.Querier

NewQuerier is the module level router for state queries

func RegisterCodec added in v0.0.5 

func RegisterCodec(cdc *codec.Codec)

RegisterCodec concretes types on codec codec

func ValidateGenesis added in v0.1.1 

func ValidateGenesis(data GenesisState) error

ValidateGenesis validates the provided oracle genesis state to ensure the expected invariants holds. (i.e. params in correct bounds, no duplicate validators)

Types

type GenesisState added in v0.1.1 

type GenesisState struct {
	Params Params `json:"params"` // market params
}

GenesisState - all distribution state that must be provided at genesis

func DefaultGenesisState added in v0.1.1 

func DefaultGenesisState() GenesisState

get raw genesis raw message for testing

func ExportGenesis added in v0.1.1 

func ExportGenesis(ctx sdk.Context, keeper Keeper) GenesisState

ExportGenesis returns a GenesisState for a given context and keeper. The GenesisState will contain the pool, and validator/delegator distribution info's

func NewGenesisState added in v0.1.1 

func NewGenesisState(params Params) GenesisState

type Keeper 

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

Keeper holds data structures for the market module

func NewKeeper 

func NewKeeper(cdc *codec.Codec, key sdk.StoreKey, ok OracleKeeper, mk MintKeeper, paramspace params.Subspace) Keeper

NewKeeper creates a new Keeper for the market module

func (Keeper) ComputeLunaDelta added in v0.2.0 

func (k Keeper) ComputeLunaDelta(ctx sdk.Context, change sdk.Int) sdk.Dec

ComputeLunaDelta returns the issuance rate change of Luna for the day post-swap

func (Keeper) GetParams added in v0.1.1 

func (k Keeper) GetParams(ctx sdk.Context) Params

GetParams get budget params from the global param store

func (Keeper) GetSwapCoin added in v0.2.0 

func (k Keeper) GetSwapCoin(ctx sdk.Context, offerCoin sdk.Coin, askDenom string, isInternal bool) (retCoin sdk.Coin, spread sdk.Dec, err sdk.Error)

GetSwapCoin returns the amount of asked coins should be returned for a given offerCoin at the effective exchange rate registered with the oracle. Returns an Error if the swap is recursive, or the coins to be traded are unknown by the oracle, or the amount to trade is too small. Ignores caps and spreads if isInternal = true.

func (Keeper) GetSwapDecCoin added in v0.2.0 

func (k Keeper) GetSwapDecCoin(ctx sdk.Context, offerCoin sdk.DecCoin, askDenom string) (sdk.DecCoin, sdk.Error)

GetSwapDecCoin returns the amount of asked DecCoins should be returned for a given offerCoin at the effective exchange rate registered with the oracle. Different from swapcoins, SwapDecCoins does not charge a spread as its use is system internal. Similar to SwapCoins, but operates over sdk.DecCoins for convenience and accuracy.

func (Keeper) SetParams added in v0.1.1 

func (k Keeper) SetParams(ctx sdk.Context, params Params)

SetParams set budget params from the global param store
