Functions

func NewBlake2b

func NewBlake2b() hash.Hash

NewBlake2b return blake2b-256 hash.

Types

type Address

type Address common.Address

Address address of account.

func BytesToAddress

func BytesToAddress(b []byte) Address

BytesToAddress converts bytes slice into address. If b is larger than address legnth, b will be cropped (from the left). If b is smaller than address length, b will be extended (from the left).

func MustParseAddress

func MustParseAddress(s string) Address

MustParseAddress convert string presented address into Address type, panic on error.

func ParseAddress

func ParseAddress(s string) (Address, error)

ParseAddress convert string presented address into Address type.

func (Address) Bytes

func (a Address) Bytes() []byte

Bytes returns byte slice form of address.

func (Address) String

func (a Address) String() string

String implements the stringer interface

type Bytes32

type Bytes32 [32]byte

Bytes32 array of 32 bytes.

func Blake2b

func Blake2b(data ...[]byte) (b32 Bytes32)

Blake2b computes blake2b-256 checksum for given data.

func MustParseBytes32

func MustParseBytes32(s string) Bytes32

MustParseBytes32 convert string presented into Bytes32 type, panic on error.

func ParseBytes32

func ParseBytes32(s string) (Bytes32, error)

ParseBytes32 convert string presented into Bytes32 type

func (Bytes32) Bytes

func (b Bytes32) Bytes() []byte

Bytes returns byte slice form of Bytes32.

func (Bytes32) String

func (b Bytes32) String() string

String implements stringer

type StorageSize

type StorageSize int64

StorageSize describes storage size in bytes.

func (StorageSize) Int64

func (ss StorageSize) Int64() int64

Int64 returns int64 value.

func (StorageSize) String

func (ss StorageSize) String() string

func (*StorageSize) Write

func (ss *StorageSize) Write(b []byte) (int, error)

Write implements io.Writer, so it can be passed into function that accepts io.Writer to count written bytes.
