Functions ¶
func FromHex ¶
FromHex returns the bytes represented by the hexadecimal string s. s may be prefixed with "0x".
func IsHexAddress ¶
IsHexAddress verifies whether a string can represent a valid hex-encoded Ethereum address or not.
Types ¶
type Address ¶
type Address [AddressLength]byte
Address represents the 20 byte address of an Ethereum account.
func BigToAddress ¶
BigToAddress returns Address with byte values of b. If b is larger than len(h), b will be cropped from the left.
func BytesToAddress ¶
BytesToAddress returns Address with value b. If b is larger than len(h), b will be cropped from the left.
func HexToAddress ¶
HexToAddress returns Address with byte values of s. If s is larger than len(h), s will be cropped from the left.
func (Address) MarshalText ¶
MarshalText returns the hex representation of a.
func (*Address) SetBytes ¶
SetBytes sets the address to the value of b. If b is larger than len(a), b will be cropped from the left.
func (*Address) UnmarshalJSON ¶
UnmarshalJSON parses a hash in hex syntax.
func (*Address) UnmarshalText ¶
UnmarshalText parses a hash in hex syntax.
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) MarshalText ¶
MarshalText returns the hex representation of h.
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) UnmarshalJSON ¶
UnmarshalJSON parses a hash in hex syntax.
func (*Hash) UnmarshalText ¶
UnmarshalText parses a hash in hex syntax.
