Types

type Config

type Config struct {
	Blocks     int
	Percentile int
	Default    *big.Int `toml:",omitempty"`
	MaxPrice   *big.Int `toml:",omitempty"`
}

type Oracle

type Oracle struct {
	// contains filtered or unexported fields
}

Oracle recommends energy prices based on the content of recent blocks. Suitable for both light and full clients.

func NewOracle

func NewOracle(backend OracleBackend, params Config) *Oracle

NewOracle returns a new energyprice oracle which can recommend suitable energyprice for newly created transaction.

func (*Oracle) SuggestPrice

func (gpo *Oracle) SuggestPrice(ctx context.Context) (*big.Int, error)

SuggestPrice returns a energyprice so that newly created transaction can have a very high chance to be included in the following blocks.

type OracleBackend

type OracleBackend interface {
	HeaderByNumber(ctx context.Context, number rpc.BlockNumber) (*types.Header, error)
	BlockByNumber(ctx context.Context, number rpc.BlockNumber) (*types.Block, error)
	ChainConfig() *params.ChainConfig
