Functions

func ArgumentTypeName 

func ArgumentTypeName(argumentType ArgumentType) string

func BindArguments 

func BindArguments(arguments []Argument, expected []reflect.Type) ([]any, error)

func BindArgumentsWithTransfers 

func BindArgumentsWithTransfers(arguments []Argument, expected []reflect.Type, files map[uint64]gox.File) ([]any, error)

func DecodeBigInt 

func DecodeBigInt(data []byte) (*big.Int, error)

DecodeBigInt decodes one canonical BIGINT argument without limiting its precision to uint64.

func DecodeCompactUint 

func DecodeCompactUint(data []byte) (uint64, int, error)

DecodeCompactUint decodes one canonical compact uint and returns how many bytes were consumed.

func DecodeFileReference 

func DecodeFileReference(data []byte) (uint64, error)

func DecodeFilesReference 

func DecodeFilesReference(data []byte) ([]uint64, error)

func EncodeArguments 

func EncodeArguments(arguments []Argument) ([]byte, error)

func EncodeBigInt 

func EncodeBigInt(value *big.Int) ([]byte, error)

EncodeBigInt creates the canonical decimal payload of one BIGINT argument.

func EncodeCompactUint 

func EncodeCompactUint(value uint64) []byte

EncodeCompactUint encodes a uint64 as a width byte followed by the minimum number of big-endian bytes. Zero is encoded as one zero byte.

func EncodeFileReference 

func EncodeFileReference(transferID uint64) ([]byte, error)

EncodeFileReference creates the payload of one FILE argument.

func EncodeFilesReference 

func EncodeFilesReference(transferIDs []uint64) ([]byte, error)

EncodeFilesReference creates the payload of one FILES argument while preserving the original file order.

func EncodePacket 

func EncodePacket(packet Packet) ([]byte, error)

func EncodeValuesWithTransfers 

func EncodeValuesWithTransfers(values []any, allocate func() uint64, clients ...gox.ClientIslandRuntime) ([]Argument, []Transfer, error)

EncodeValuesWithTransfers encodes event values and extracts file bodies into independent transfers referenced by FILE and FILES arguments.

func EventName 

func EventName(packet Packet) string

func HeaderText 

func HeaderText(packet Packet, headerType HeaderType) string

func HeaderUint 

func HeaderUint(packet Packet, headerType HeaderType) (uint64, bool)
