Types

type Account 

type Account struct {
	Nonce    uint32
	Epoch    uint16
	Balance  *big.Int
	Contract *ContractData
}

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

func (*Account) FromBytes added in v0.21.0 

func (a *Account) FromBytes(data []byte) error

func (*Account) ToBytes added in v0.21.0 

func (a *Account) ToBytes() ([]byte, error)

	Approved bool
	Online   bool
}

func (*ApprovedIdentity) FromBytes added in v0.21.0 

func (s *ApprovedIdentity) FromBytes(data []byte) error

func (*ApprovedIdentity) ToBytes added in v0.21.0 

func (s *ApprovedIdentity) ToBytes() ([]byte, error)

type BitArray 

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 

func NewBitArray(bits int) *BitArray

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

func (*BitArray) Bytes 

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

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

func (*BitArray) GetIndex 

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 

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 

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 

func (bA *BitArray) Size() uint

Size returns the number of bits in the bitarray

func (*BitArray) String 

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 

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 

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

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