Types

type BoundContract

type BoundContract struct {
	*bind.BoundContract
	// contains filtered or unexported fields
}

func BindContract

func BindContract(client *client.Client, contract *sol.Contract) (*BoundContract, error)

func (*BoundContract) ABI

func (contract *BoundContract) ABI() abi.ABI

func (*BoundContract) Address

func (contract *BoundContract) Address() common.Address

func (*BoundContract) Client

func (contract *BoundContract) Client() *client.Client

func (*BoundContract) DeployContract

func (c *BoundContract) DeployContract(opts *bind.TransactOpts,
	params ...interface{}) (common.Address, *types.Transaction, error)

DeployContract deploys a contract onto the Ethereum blockchain and binds the deployment address with a Go wrapper.

func (*BoundContract) SetAddress

func (contract *BoundContract) SetAddress(address common.Address)

func (*BoundContract) SetClient

func (contract *BoundContract) SetClient(client *client.Client)

func (*BoundContract) SetTransact

func (contract *BoundContract) SetTransact(fn TransactFunc)

func (*BoundContract) Source

func (contract *BoundContract) Source() *sol.Contract

func (*BoundContract) Transact

func (c *BoundContract) Transact(opts *bind.TransactOpts, method string, params ...interface{}) (*types.Transaction, error)

Transact invokes the (paid) contract method with params as input values.

func (*BoundContract) Transfer

func (c *BoundContract) Transfer(opts *bind.TransactOpts) (*types.Transaction, error)

Transfer initiates a plain transaction to move funds to the contract, calling its default method if one is available.

type KeyCache

type KeyCache interface {
	SetPath(account common.Address, path string) bool
	UnsetPath(account common.Address, path string)
	PrivateKey(account common.Address, password string) (key *ecdsa.PrivateKey, ok bool)
	SetPrivateKey(account common.Address, pk *ecdsa.PrivateKey)
	UnsetKey(account common.Address, password string)
	SignerFn(account common.Address, password string) bind.SignerFn
}

func NewKeyCache

func NewKeyCache() KeyCache

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 uint64)
	Get(account common.Address) uint64
	Incr(account common.Address) uint64
	Decr(account common.Address) uint64
}

func NewNonceCache

func Ston

func Ston(ston uint64) *Peb

func StringPeb

func StringPeb(str string) *Peb

func ToPeb

func ToPeb(amount float64) *Peb

ToPeb converts Klay or tokens amount into Peb amount.

func (*Peb) Add

func (p *Peb) Add(amount *Peb) *Peb

Add adds two amounts togKlay and returns a new amount.

func (Peb) Bytes

func (p *Peb) SplitEqual(parts int) []*Peb

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 (*Peb) Ston

func (p *Peb) Ston() uint64

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

	chainID int,
	klayClient *client.Client,
	klayFeeClient klayfee.FeeDelegationClient,
) TransactFunc

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.
