Types ¶
type Decoder ¶
type Decoder struct {
// contains filtered or unexported fields
}
Decoder decodes events relevant to the fillability of 0x orders. Since ERC20 & ERC721 events have the same signatures, but different meanings, all ERC20 & ERC721 contract addresses must be added to the decoder ahead of time.
func (*Decoder) AddKnownERC1155 ¶
AddKnownERC1155 registers the supplied contract address as an ERC1155 contract. If an event is found from this contract address, the decoder will properly decode the `Transfer` and `Approve` events including the correct event parameter names.
func (*Decoder) AddKnownERC20 ¶
AddKnownERC20 registers the supplied contract address as an ERC20 contract. If an event is found from this contract address, the decoder will properly decode the `Transfer` and `Approve` events including the correct event parameter names.
func (*Decoder) AddKnownERC721 ¶
AddKnownERC721 registers the supplied contract address as an ERC721 contract. If an event is found from this contract address, the decoder will properly decode the `Transfer` and `Approve` events including the correct event parameter names.
func (*Decoder) AddKnownExchange ¶
AddKnownExchange registers the supplied contract address as a 0x Exchange contract. If an event is found from this contract address, the decoder will properly decode it's events including the correct event parameter names.
func (*Decoder) Decode ¶
Decode attempts to decode the supplied log given the event types relevant to 0x orders. The decoded result is stored in the value pointed to by supplied `decodedLog` struct.
func (*Decoder) FindEventType ¶
FindEventType returns to event type contained in the supplied log. It looks both at the registered contract addresses and the log topic.
func (*Decoder) RemoveKnownERC1155 ¶
RemoveKnownERC1155 removes an ERC1155 address from the list of known addresses. We will no longer decode events for this token.
func (*Decoder) RemoveKnownERC20 ¶
RemoveKnownERC20 removes an ERC20 address from the list of known addresses. We will no longer decode events for this token.
func (*Decoder) RemoveKnownERC721 ¶
RemoveKnownERC721 removes an ERC721 address from the list of known addresses. We will no longer decode events for this token.
