Functions ¶
func AddressTo32Bytes ¶
AddressTo32Bytes converts an address to 32 a byte array The length of an address is 20 bytes. First 12 bytes are filled with zeros.
func Byte32ToSlice ¶
Byte32ToSlice converts a [32]bytes to an unbounded byte array
func ByteArrayTo32BytesLeftPadded ¶
ByteArrayTo32BytesLeftPadded converts an address to 32 a byte array The length of the input has to be less or equals to 32
func ByteFixedToBigInt ¶
ByteFixedToBigInt convert arbitrary length byte arrays to big.Int
func ByteSliceToBigInt ¶
ByteSliceToBigInt convert bute slices to big.Int (bigendian)
func Check32BytesFilled ¶
Check32BytesFilled ensures byte slice is of length 32 and don't contain all 0x0 bytes.
func CheckMultiple32BytesFilled ¶
CheckMultiple32BytesFilled takes multiple []byte slices and ensures they are all of length 32 and don't contain all 0x0 bytes.
func ContainsBigIntInSlice ¶
ContainsBigIntInSlice checks if value is present in list.
func ContainsString ¶
ContainsString returns true if the slice contains str.
func ConvertByte32ToInt ¶
ConvertByte32ToInt converts a fixed length byte array into int with BigEndian order
func ConvertIntToByte32 ¶
ConvertIntToByte32 converts an integer into a fixed length byte array with BigEndian order
func ConvertProofForEthereum ¶
ConvertProofForEthereum converts a proof to 32 byte format needed by ethereum
func FromTimestamp ¶
FromTimestamp converts a timestamp protobuf to time
func GetCentLogFormat ¶
func GetCentLogFormat() string
GetCentLogFormat returns the specific log format
func GetFreeAddrPort ¶
GetFreeAddrPort returns a loopback address and port that can be listened from. Note: port is included in the address.
func InRange ¶ added in v1.0.0
InRange returns a boolean if the given number is in between a specified range.
func IsEmptyAddress ¶
IsEmptyAddress checks if the addr is empty.
func IsEmptyByte32 ¶
IsEmptyByte32 checks if the source is empty.
func IsEmptyByteSlice ¶
IsEmptyByteSlice checks if the provided slice is empty returns true if: s == nil every element is == 0
func IsSameByteSlice ¶
IsSameByteSlice checks if a and b contains same bytes.
func IsStringEmpty ¶
IsStringEmpty returns true if the string is empty
func IsStringOfLength ¶
IsStringOfLength returns true if length of the string == n
func IsValidByteSliceForLength ¶
IsValidByteSliceForLength checks if the len(slice) == length.
func LookForEvent ¶
func LookForEvent(iter EventIterator) (err error)
LookForEvent checks if the iterator is ready with the Event if no event is found, returns ErrEventNotFound returns iter.Error when iterator errored out
func MustSliceToByte32 ¶ added in v1.0.0
MustSliceToByte32 converts the bytes to byte 32 panics if the input length is > 32 bytes.
func RandomBigInt ¶ added in v1.0.0
RandomBigInt returns a random big int that's less than the provided max.
func RandomByte32 ¶

func SendPOSTRequest ¶
SendPOSTRequest sends post with data to given URL.
func SimulateJSONDecodeForGocelery ¶
SimulateJSONDecodeForGocelery encodes and decodes the kwargs.
func SliceOfByteSlicesToHexStringSlice ¶
SliceOfByteSlicesToHexStringSlice converts the given slice of byte slices to a hex encoded string array with 0x prefix
func SliceToByte32 ¶
SliceToByte32 converts a 32 byte slice to an array. Will throw error if the slice is too long
func ToTimestamp ¶
