Functions ¶
func NewMsgServerImpl ¶
NewMsgServerImpl returns an implementation of the MsgServer interface for the provided Keeper.
Types ¶
type ActivePairsState ¶ added in v0.5.2
type ActivePairsState Keeper
----------------------------------------------------------------------------- ActivePairsState implements methods for updating the "active pairs" sdk.KVStore
func (ActivePairsState) AddActivePairs ¶ added in v0.5.2
func (state ActivePairsState) AddActivePairs( ctx sdk.Context, pairs []common.AssetPair, )
func (ActivePairsState) Iterate ¶ added in v0.5.2
func (state ActivePairsState) Iterate( ctx sdk.Context, do func(*types.ActivePairMarshaler) (stop bool), )
func (ActivePairsState) Set ¶ added in v0.5.2
ActivePairsState.Set either sets a pair to active or deletes it from the
key-value store (i.e., pairs default to inactive if they don't exist).
func (ActivePairsState) SetMany ¶ added in v0.5.2
func (state ActivePairsState) SetMany( ctx sdk.Context, pairs common.AssetPairs, active bool, )
type Keeper ¶
type Keeper struct {
// contains filtered or unexported fields
}
func NewKeeper ¶
func NewKeeper( cdc codec.BinaryCodec, storeKey, memKey storetypes.StoreKey, ps paramtypes.Subspace, ) Keeper
func (Keeper) ActivePairsStore ¶ added in v0.5.2
func (k Keeper) ActivePairsStore() ActivePairsState
ActivePairsStore maintains the "active pairs" KVStore: maps pair name → isActive. If a pair doesn't have a key in the store, the pair is inactive.
func (Keeper) CalculateMedianPrice ¶
func (k Keeper) CalculateMedianPrice(prices []types.CurrentPrice) sdk.Dec
CalculateMedianPrice calculates the median prices for the input prices.
func (Keeper) GetCurrentPrice ¶
func (k Keeper) GetCurrentPrice(ctx sdk.Context, token0 string, token1 string, ) (currPrice types.CurrentPrice, err error)
GetCurrentPrice fetches the current median price of all oracles for a specific market
func (Keeper) GetCurrentPrices ¶
func (k Keeper) GetCurrentPrices(ctx sdk.Context) types.CurrentPrices
GetCurrentPrices returns all current price objects from the store
func (Keeper) GetCurrentTWAPPrice ¶
func (k Keeper) GetCurrentTWAPPrice(ctx sdk.Context, token0 string, token1 string) (currPrice types.CurrentTWAP, err error)
GetCurrentTWAPPrice fetches the current median price of all oracles for a specific market
func (Keeper) GetOraclesForPair ¶ added in v0.5.2
GetOraclesForPair returns the oracles for a valid asset pair
func (Keeper) GetOraclesForPairs ¶ added in v0.5.2
func (k Keeper) GetOraclesForPairs(ctx sdk.Context, pairs common.AssetPairs, ) map[common.AssetPair][]sdk.AccAddress
GetOraclesForPairs returns the 'oraclesMatrix' corresponding to 'pairs'. 'oraclesMap' is a map from pair → list of oracles. This function effectively gives a subset of the OraclesState KVStore.
func (Keeper) GetPairs ¶
func (k Keeper) GetPairs(ctx sdk.Context) common.AssetPairs
GetPairs returns the pairs from params
func (Keeper) GetRawPrices ¶
GetRawPrices fetches the set of all prices posted by oracles for an asset
func (Keeper) IsActivePair ¶ added in v0.5.2
GetPair returns the market if it is in the pricefeed system
func (Keeper) IsWhitelistedOracle ¶ added in v0.5.2
IsWhitelistedOracle returns true if the address is whitelisted, false if not.
func (Keeper) IterateCurrentPrices ¶
IterateCurrentPrices iterates over all current price objects in the store and performs a callback function
func (Keeper) IterateRawPricesByPair ¶
func (k Keeper) IterateRawPricesByPair(ctx sdk.Context, marketId string, cb func(record types.PostedPrice) (stop bool))
IterateRawPrices iterates over all raw prices in the store and performs a callback function
func (Keeper) OraclesStore ¶ added in v0.5.2
func (k Keeper) OraclesStore() OraclesState
OraclesStore maintains the "oracles" KVStore: maps pair name → oracles.
func (Keeper) QueryMarkets ¶ added in v0.6.0
func (k Keeper) QueryMarkets(goCtx context.Context, req *types.QueryMarketsRequest, ) (*types.QueryMarketsResponse, error)
func (Keeper) QueryOracles ¶ added in v0.5.2

func (Keeper) QueryParams ¶ added in v0.5.2
func (k Keeper) QueryParams(c context.Context, req *types.QueryParamsRequest, ) (*types.QueryParamsResponse, error)
func (Keeper) QueryPrice ¶ added in v0.5.2
func (k Keeper) QueryPrice(goCtx context.Context, req *types.QueryPriceRequest) (*types.QueryPriceResponse, error)
func (Keeper) QueryPrices ¶ added in v0.5.2
