var EmptyString = &hexError{"empty hex string"}
EmptyString is the error returned when decoding an empty hex string.
Functions ¶
func BytesToHexString ¶
BytesToHexString encodes bytes as a hex string.
func DecodeCheck ¶
DecodeCheck decodes a Base58Check string, validates the checksum and TRON prefix (0x41), and returns the decoded bytes (prefix + 20-byte address payload) without the checksum.
func EnableAllVerbose ¶
func EnableAllVerbose()
EnableAllVerbose enables all debug logging flags (gRPC and transaction).
func EncodeCheck ¶
EncodeCheck returns the Base58Check encoding of input (Base58 with a 4-byte SHA-256d checksum).
func FromHex ¶
FromHex returns the bytes represented by the hexadecimal string s. s may be prefixed with "0x".
func Has0xPrefix ¶
Has0xPrefix validates str begins with '0x' or '0X'.
func Hex2BytesFixed ¶
Hex2BytesFixed returns bytes of a specified fixed length flen.
func HexStringToBytes ¶
HexStringToBytes decodes a hex string (with or without "0x" prefix) into bytes.
func JSONPrettyFormat ¶
JSONPrettyFormat returns the JSON string indented for readability.
func LeftPadBytes ¶
LeftPadBytes zero-pads slice to the left up to length l.
func RightPadBytes ¶
RightPadBytes zero-pads slice to the right up to length l.
func ToHexArray ¶
ToHexArray converts each byte slice in b to a "0x"-prefixed hex string.
func ToJSONUnsafe ¶
ToJSONUnsafe marshals payload to JSON, returning "{}" on failure.
func TrimLeftZeroes ¶
TrimLeftZeroes returns a subslice of s without leading zero bytes.
Types ¶
type Hash ¶
type Hash [HashLength]byte
Hash represents the 32 byte Keccak256 hash of arbitrary data.
func BigToHash ¶
BigToHash sets byte representation of b to hash. If b is larger than len(h), b will be cropped from the left.
func BytesToHash ¶
BytesToHash sets b to hash. If b is larger than len(h), b will be cropped from the left.
func HexToHash ¶
HexToHash sets byte representation of s to hash. If b is larger than len(h), b will be cropped from the left.
func (*Hash) SetBytes ¶
SetBytes sets the hash to the value of b. If b is larger than len(h), b will be cropped from the left.
func (Hash) String ¶
String implements the stringer interface and is used also by the logger when doing full logging into a file.
func (Hash) TerminalString ¶
TerminalString implements log.TerminalStringer, formatting a string for console output during logging.
