Functions

func GenerateEvent

func GenerateEvent(
	type_ EventType,
	from, to, admin string,
	asset xdr.Asset,
	amount *big.Int,
	passphrase string,
) xdr.ContractEvent

GenerateEvent is a utility function to be used by testing frameworks in order to generate Hcnet Asset Contract events.

To provide a generic interface, there are more arguments than apply to the type, but you should only expect the relevant ones to be set (for example, transfer events have no admin, so it will be ignored). This means you can always pass your set of testing parameters, modify the type, and get the event filled out with the details you expect.
