Types

type Account 

type Account struct {
	Nonce        uint64
	Balance      Balances
	MultisigData Multisig
}

Account is the Minter consensus representation of accounts. These objects are stored in the main account trie.

type Balance 

type Balance struct {
	Coin   types.CoinSymbol
	Amount *big.Int
}

type BalanceChangeStruct 

type BalanceChangeStruct struct {
	Address           types.Address
	Coin              types.CoinSymbol
	Balance           *big.Int
	BalanceInBasecoin *big.Int
}

type BitArray added in v0.4.0 

type BitArray struct {
	Bits  uint     `json:"bits"`  // NOTE: persisted via reflect, must be exported
	Elems []uint64 `json:"elems"` // NOTE: persisted via reflect, must be exported
	// contains filtered or unexported fields
}

BitArray is a thread-safe implementation of a bit array.

func NewBitArray added in v0.4.0 

func NewBitArray(bits int) *BitArray

NewBitArray returns a new bit array. It returns nil if the number of bits is zero.

func (*BitArray) Bytes added in v0.4.0 

func (bA *BitArray) Bytes() []byte

Bytes returns the byte representation of the bits within the bitarray.

func (*BitArray) GetIndex added in v0.4.0 

func (bA *BitArray) GetIndex(i int) bool

GetIndex returns the bit at index i within the bit array. The behavior is undefined if i >= bA.Bits

func (*BitArray) MarshalJSON added in v0.4.0 

func (bA *BitArray) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler interface by marshaling bit array using a custom format: a string of '-' or 'x' where 'x' denotes the 1 bit.

func (*BitArray) SetIndex added in v0.4.0 

func (bA *BitArray) SetIndex(i int, v bool) bool

SetIndex sets the bit at index i within the bit array. The behavior is undefined if i >= bA.Bits

func (bA *BitArray) Size() uint

Size returns the number of bits in the bitarray

func (*BitArray) String added in v0.4.0 

func (bA *BitArray) String() string

String returns a string representation of BitArray: BA{<bit-string>}, where <bit-string> is a sequence of 'x' (1) and '_' (0). The <bit-string> includes spaces and newlines to help people. For a simple sequence of 'x' and '_' characters with no spaces or newlines, see the MarshalJSON() method. Example: "BA{_x_}" or "nil-BitArray" for nil.

func (*BitArray) StringIndented added in v0.4.0 

func (bA *BitArray) StringIndented(indent string) string

StringIndented returns the same thing as String(), but applies the indent at every 10th bit, and twice at every 50th bit.

func (*BitArray) UnmarshalJSON added in v0.4.0 

func (bA *BitArray) UnmarshalJSON(bz []byte) error

UnmarshalJSON implements json.Unmarshaler interface by unmarshaling a custom JSON description.
