Functions

func EmitBalanceChange 

func EmitBalanceChange(address types.Address, coin types.CoinSymbol, balance *big.Int)

Types

type Account 

type Account struct {
	Nonce   uint64
	Balance Balances
	Root    types.Hash // merkle root of the storage trie
}

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

	Coin   types.CoinSymbol
	Amount *big.Int
}

type BalanceChangeStruct struct {
	Address           types.Address

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) And added in v0.4.0 

func (bA *BitArray) And(o *BitArray) *BitArray

And returns a bit array resulting from a bitwise AND of the two bit arrays. If the two bit-arrys have different lengths, this truncates the larger of the two bit-arrays from the right. Thus the size of the return value is the minimum of the two provided bit arrays.

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) Copy added in v0.4.0 

func (bA *BitArray) Copy() *BitArray

Copy returns a copy of the provided bit array.

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) IsEmpty added in v0.4.0 

func (bA *BitArray) IsEmpty() bool

IsEmpty returns true iff all bits in the bit array are 0

func (*BitArray) IsFull added in v0.4.0 

func (bA *BitArray) IsFull() bool

IsFull returns true iff all bits in the bit array are 1.

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) Not added in v0.4.0 

func (bA *BitArray) Not() *BitArray

Not returns a bit array resulting from a bitwise Not of the provided bit array.

func (*BitArray) Or added in v0.4.0 

func (bA *BitArray) Or(o *BitArray) *BitArray

Or returns a bit array resulting from a bitwise OR of the two bit arrays. If the two bit-arrys have different lengths, Or right-pads the smaller of the two bit-arrays with zeroes. Thus the size of the return value is the maximum of the two provided bit arrays.

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 (*BitArray) Size added in v0.4.0 

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) Sub added in v0.4.0 

func (bA *BitArray) Sub(o *BitArray) *BitArray

Sub subtracts the two bit-arrays bitwise, without carrying the bits. This is essentially bA.And(o.Not()). If bA is longer than o, o is right padded with zeroes.

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.

func (*BitArray) Update added in v0.4.0 

func (bA *BitArray) Update(o *BitArray)

Update sets the bA's bits to be that of the other bit array. The copying begins from the begin of both bit arrays.
