Functions​

invalidatorForOrderRFQ​

function invalidatorForOrderRFQ(
  address maker,
  uint256 slot
) external returns (uint256)

Returns bitmask for double-spend invalidators based on lowest byte of order.info and filled quotes

Parameters:​

Name	Type	Description
maker	address
slot	uint256

Return Values:​

Name	Type	Description
Result	uint256	Each bit represents whether corresponding was already invalidated

cancelOrderRFQ​

function cancelOrderRFQ(
  uint256 orderInfo
) external

Cancels order's quote

Parameters:​

Name	Type	Description
orderInfo	uint256

fillOrderRFQ​

function fillOrderRFQ(
  struct OrderRFQMixin.Order order,
  bytes signature,
  uint256 makingAmount,
  uint256 takingAmount
) external returns (uint256, uint256)

Fills order's quote, fully or partially (whichever is possible)

Parameters:​

Name	Type	Description
order	struct OrderRFQMixin.Order	Order quote to fill
signature	bytes	Signature to confirm quote ownership
makingAmount	uint256	Making amount
takingAmount	uint256	Taking amount

fillOrderRFQToWithPermit​

function fillOrderRFQToWithPermit(
  struct OrderRFQMixin.Order order,
  bytes signature,
  uint256 makingAmount,
  uint256 takingAmount,
  address target,
  bytes permit
) external returns (uint256, uint256)

Fills Same as fillOrderRFQ but calls permit first, allowing to approve token spending and make a swap in one transaction. Also allows to specify funds destination instead of msg.sender

See tests for examples

Parameters:​

Name	Type	Description
order	struct OrderRFQMixin.Order	Order quote to fill
signature	bytes	Signature to confirm quote ownership
makingAmount	uint256	Making amount
takingAmount	uint256	Taking amount
target	address	Address that will receive swap funds
permit	bytes	Should consist of abiencoded token address and encoded IERC20Permit.permit call.

fillOrderRFQTo​

function fillOrderRFQTo(
  struct OrderRFQMixin.Order order,
  bytes signature,
  uint256 makingAmount,
  uint256 takingAmount,
  address target
) public returns (uint256, uint256)

Same as fillOrderRFQ but allows to specify funds destination instead of msg.sender

Parameters:​

Name	Type	Description
order	struct OrderRFQMixin.Order	Order quote to fill
signature	bytes	Signature to confirm quote ownership
makingAmount	uint256	Making amount
takingAmount	uint256	Taking amount
target	address	Address that will receive swap funds

Events​

OrderFilledRFQ​

event OrderFilledRFQ(
  bytes32 orderHash,
  uint256 makingAmount
)

Emitted when RFQ gets filled

Parameters:​

Name	Type	Description
orderHash	bytes32
makingAmount	uint256
