type Contract

type Contract struct {
	Name            string
	SourcePath      string
	CompilerVersion string
	Address         common.Address

	ABI []byte
	Bin string
}

type NonceCache

type NonceCache interface {
	Serialize(account common.Address, fn func() error) error
	Sync(account common.Address, syncFn func() (uint64, error))

	Set(account common.Address, nonce int64)
	Get(account common.Address) int64
	Incr(account common.Address) int64
	Decr(account common.Address) int64
}

func NewNonceCache

func NewNonceCache() NonceCache

type TransactFunc

type TransactFunc func(opts *bind.TransactOpts, contract *common.Address, input []byte) (*types.Transaction, error)

type Uniquify

type Uniquify interface {
	// Call executes only one callable with same id at a time.
	// Multilpe asynchronous calls with same id will be executed sequentally.
	Call(id string, callable func() error) error
}

Uniquify is a type of advanced mutex. It allows to create named resource locks.

func NewUniquify

func NewUniquify() Uniquify

NewUniquify returns a new thread-safe uniquify object.

type Wei

type Wei decimal.Decimal

func BigWei

func BigWei(w *big.Int) *Wei

func DecimalToWei

func DecimalToWei(d decimal.Decimal) *Wei

func DecimalWei

func DecimalWei(d decimal.Decimal) *Wei

func Gwei

func Gwei(gwei uint64) *Wei

func StringWei

func StringWei(str string) *Wei

func ToWei

func ToWei(amount float64) *Wei

ToWei converts ether or tokens amount into Wei amount.

func (*Wei) Add

func (w *Wei) Add(amount *Wei) *Wei

Add adds two amounts together and returns a new amount.

func (Wei) Bytes

func (w Wei) Bytes() []byte

func (*Wei) Div

func (w *Wei) Div(m int64) *Wei

func (*Wei) Ether

func (w *Wei) Ether() float64

func (*Wei) Gwei

func (w *Wei) Gwei() uint64

Gwei is an unsafe way to represent Wei as uint64, used for gas price reporting and should not be used for math.

func (w *Wei) Mul(m int64) *Wei

func (*Wei) Scan

func (w *Wei) Scan(v interface{}) error

func (*Wei) SplitEqual

func (w *Wei) SplitEqual(parts int) []*Wei

SplitEqual splits the amount into n-1 equal amounts and one remainder. Example: (1000).SplitEqual(7) yields [142 142 142 142 142 142 148]

func (Wei) String

func (w Wei) String() string

func (Wei) StringGwei

func (w Wei) StringGwei() string

func (w *Wei) Sub(amount *Wei) *Wei

Sub substracts two amounts and returns a new amount.

func (*Wei) ToInt

func (w *Wei) ToInt() *big.Int

func (*Wei) Tokens

func (w *Wei) Tokens() float64
