Functions

func GetErrorFromUpdateResults 

func GetErrorFromUpdateResults(
	success bool,
	successPerUpdate []UpdateResult,
	updates []Update,
) error

GetErrorFromUpdateResults generates a helpful error when UpdateSubaccounts or CanUpdateSubaccounts returns one or more failed updates.

func NewCreateSettledFundingEvent 

func NewCreateSettledFundingEvent(
	subaccount SubaccountId,
	perpetualId uint32,
	fundingPaid *big.Int,
) sdk.Event

NewCreateSettledFundingEvent constructs a new funding sdk.Event. Note that `fundingPaid` is positive if the subaccount paid funding, negative if the subaccount received funding.

func RegisterCodec 

func RegisterCodec(cdc *codec.LegacyAmino)

func RegisterInterfaces 

func RegisterInterfaces(registry cdctypes.InterfaceRegistry)

func RegisterQueryHandler 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer 

func RegisterQueryServer(s grpc1.Server, srv QueryServer)

type SortedSubaccountIds 

type SortedSubaccountIds []SubaccountId

SortedSubaccountIds is type alias for `[]SubaccountId` which supports deterministic sorting. SubaccountIds are first ordered by string comparison of their `Owner`, followed by integer comparison of their `Number`. If two `SubaccountId` have equal Owners, and Numbers, they are assumed to be equal, and their sorted order is not deterministic.

	// Always sorted ascending by `asset_id`.
	AssetPositions []*AssetPosition `protobuf:"bytes,2,rep,name=asset_positions,json=assetPositions,proto3" json:"asset_positions,omitempty"`

	// subaccount.
	MarginEnabled bool `protobuf:"varint,4,opt,name=margin_enabled,json=marginEnabled,proto3" json:"margin_enabled,omitempty"`
}
