Functions

func BytesToHex

func BytesToHex(b []byte) string

BytesToHex converts the given slice of bytes to a hex string with a "0x" prefix. If b is nil or has length 0, it returns "0x".

func HexToBytes

func HexToBytes(s string) []byte

HexToBytes converts the the given hex string (with or without the "0x" prefix) to a slice of bytes. If the string is "0x" it returns nil.

Types

type AddOrdersOpts

type AddOrdersOpts struct {
	// Pinned determines whether or not the added orders should be pinned. Pinned
	// orders will not be affected by any DDoS prevention or incentive mechanisms
	// and will always stay in storage until they are no longer fillable. Defaults
	// to true.
	Pinned bool `json:"pinned"`
	// KeepCancelled signals that this order should not be deleted
	// even if it is cancelled.
	KeepCancelled bool `json:"keepCancelled"`
	// KeepExpired signals that this order should not be deleted
	// even if it becomes expired.
	KeepExpired bool `json:"keepExpired"`
	// KeepFullyFilled signals that this order should not be deleted
	// even if it is fully filled.
	KeepFullyFilled bool `json:"keepFullyFilled"`
	// KeepUnfunded signals that this order should not be deleted
	// even if it becomes unfunded.
	KeepUnfunded bool `json:"keepUnfunded"`
}

AddOrdersOpts is a set of options for core.AddOrders. Also used in the browser interface.

type GetOrdersResponse

type GetOrdersResponse struct {
	Timestamp   time.Time    `json:"timestamp"`
	OrdersInfos []*OrderInfo `json:"ordersInfos"`
}

GetOrdersResponse is the return value for core.GetOrders. Also used in the browser interface.

type LatestBlock

type LatestBlock struct {
	Number *big.Int    `json:"number"`
	Hash   common.Hash `json:"hash"`
}

LatestBlock is the latest block processed by the Mesh node.

type Metadata

type Metadata struct {
	EthereumChainID                   int
	EthRPCRequestsSentInCurrentUTCDay int
	StartOfCurrentUTCDay              time.Time
}

	FillableTakerAssetAmount *big.Int            `json:"fillableTakerAssetAmount"`
}

OrderInfo represents an fillable order and how much it could be filled for.

func (OrderInfo) MarshalJSON

func (o OrderInfo) MarshalJSON() ([]byte, error)

MarshalJSON is a custom Marshaler for OrderInfo

func (*OrderInfo) UnmarshalJSON

func (o *OrderInfo) UnmarshalJSON(data []byte) error

UnmarshalJSON implements a custom JSON unmarshaller for the OrderEvent type

type OrderWithMetadata

type OrderWithMetadata struct {
	OrderV3 *zeroex.Order

	SignatureV4              zeroex.SignatureFieldV4 `json:"signaturev4"`
	FillableTakerAssetAmount *big.Int                `json:"fillableTakerAssetAmount"`
	LastUpdated              time.Time               `json:"lastUpdated"`
	// Was this order flagged for removal? Due to the possibility of block-reorgs, instead
	// of immediately removing an order when FillableTakerAssetAmount becomes 0, we instead
	// flag it for removal. After this order isn't updated for X time and has IsRemoved = true,
	// the order can be permanently deleted.
	IsRemoved bool `json:"isRemoved"`
	// IsPinned indicates whether or not the order is pinned. Pinned orders are
	// not removed from the database unless they become unfillable.
	IsPinned bool `json:"isPinned"`
	// IsUnfillable indicates whether or not the order has become unfillable.
	IsUnfillable bool `json:"isUnfillable"`
	// IsExpired indicates whether or not the order has become expired.
	IsExpired bool `json:"isExpired"`
	// JSON-encoded list of assetdatas contained in MakerAssetData. For non-MAP
	// orders, the list contains only one element which is equal to MakerAssetData.
	// For MAP orders, it contains each component assetdata.
	ParsedMakerAssetData []*SingleAssetData `json:"parsedMakerAssetData"`
	// Same as ParsedMakerAssetData but for MakerFeeAssetData instead of MakerAssetData.
	ParsedMakerFeeAssetData []*SingleAssetData `json:"parsedMakerFeeAssetData"`
