Functions

func NewMsgServerImpl

func NewMsgServerImpl(keeper Keeper) types.MsgServer

NewMsgServerImpl returns an implementation of the MsgServer interface for the provided Keeper.

Types

type Keeper

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

func NewKeeper

func NewKeeper(
	cdc codec.BinaryCodec,
	storeKey storetypes.StoreKey,
	pricesKeeper types.PricesKeeper,
	indexerEventManager indexer_manager.IndexerEventManager,
) *Keeper

func (Keeper) AllAssets

func (k Keeper) AllAssets(
	c context.Context,
	req *types.QueryAllAssetsRequest,
) (*types.QueryAllAssetsResponse, error)

TODO(CLOB-863) Add tests for these endpoints.

func (Keeper) Asset

func (k Keeper) Asset(c context.Context, req *types.QueryAssetRequest) (*types.QueryAssetResponse, error)

func (Keeper) ConvertAssetToCoin

func (k Keeper) ConvertAssetToCoin(
	ctx sdk.Context,
	assetId uint32,
	quantums *big.Int,
) (
	convertedQuantums *big.Int,
	coin sdk.Coin,
	err error,
)

ConvertAssetToCoin converts the given `assetId` and `quantums` used in `x/asset`, to an `sdk.Coin` in correspoding `denom` and `amount` used in `x/bank`. Also outputs `convertedQuantums` which has the equal value as converted `sdk.Coin`. The conversion is done with the formula:

denom_amount = quantums * 10^(atomic_resolution - denom_exponent)

If the resulting `denom_amount` is not an integer, it is rounded down, and `convertedQuantums` of the equal value is returned. The upstream transfer function should adjust asset balance with `convertedQuantums` to ensure that that no fund is ever lost in the conversion due to rounding error.

Example: Assume `denom_exponent` = -7, `atomic_resolution` = -8, ConvertAssetToCoin(`101 quantums`) should output: - `convertedQuantums` = 100 quantums - converted coin amount = 10 coin

func (Keeper) CreateAsset

func (k Keeper) CreateAsset(
	ctx sdk.Context,
	symbol string,
	denom string,
	denomExponent int32,
	hasMarket bool,
	marketId uint32,
	atomicResolution int32,
) (types.Asset, error)

func (Keeper) GetAllAssets

func (k Keeper) GetAllAssets(
	ctx sdk.Context,
) []types.Asset

func (Keeper) GetAsset

func (k Keeper) GetAsset(
	ctx sdk.Context,
	id uint32,
) (val types.Asset, err error)

func (Keeper) GetDenomById

func (k Keeper) GetDenomById(
	ctx sdk.Context,
	id uint32,
) (
	denom string,
	err error,
)

GetDenomById returns the `denom` of the asset with a given `id`. Returns an error if the `id` does not exist.

func (Keeper) GetIdByDenom

func (k Keeper) GetIdByDenom(
	ctx sdk.Context,
	denom string,
) (
	id uint32,
	err error,
)

GetIdByDenom returns the `id` of the asset with a given `denom`. Returns an error if the `denom` does not exist.

func (Keeper) GetIndexerEventManager

func (k Keeper) GetIndexerEventManager() indexer_manager.IndexerEventManager

func (Keeper) GetMarginRequirements

func (k Keeper) GetMarginRequirements(
	ctx sdk.Context,
	id uint32,
	bigQuantums *big.Int,
) (
	bigInitialMarginQuoteQuantums *big.Int,
	bigMaintenanceMarginQuoteQuantums *big.Int,
	err error,
)

GetMarginRequirements returns the initial and maintenance margin- requirements for a given position size for a given assetId.

func (Keeper) GetNetCollateral

func (k Keeper) GetNetCollateral(
	ctx sdk.Context,
	id uint32,
	bigQuantums *big.Int,
) (
	bigNetCollateralQuoteQuantums *big.Int,
	err error,
)

GetNetCollateral returns the net collateral that a given position (quantums) for a given assetId contributes to an account.

	ctx sdk.Context,
) uint32

func (Keeper) InitializeForGenesis

func (k Keeper) InitializeForGenesis(ctx sdk.Context)
