Functions

func DefaultGasFactor 

func DefaultGasFactor(i uint64) uint64

Types

type Client 

type Client struct {
	GasLimitFactor func(gasLimit uint64) uint64
	// contains filtered or unexported fields
}

Client is the jsonrpc client

func NewClient 

func NewClient(addr string) (*Client, error)

NewClient creates a new client

func (*Client) Call 

func (c *Client) Call(method string, out interface{}, params ...interface{}) error

Call makes a jsonrpc call

func (*Client) Close 

func (c *Client) Close() error

Close closes the tranport

func (*Client) Eth 

func (c *Client) Eth() *Eth

Eth returns the reference to the eth namespace

func (*Client) Net 

func (c *Client) Net() *Net

Net returns the reference to the net namespace

func (*Client) Subscribe 

func (c *Client) Subscribe(method string, param interface{}, callback func(b []byte)) (func() error, error)

Subscribe starts a new subscription

func (*Client) SubscribeLogs added in v0.1.2 

func (c *Client) SubscribeLogs(callback func(log *web3.Log), addresses []web3.Address, topics ...[][]web3.Hash) (func() error, error)

Emits logs which are part of newly added blocks that match specified filter criteria.

When a chain reorganization occurs, logs which are part of blocks on the old chain will be emitted again with the property removed set to true. Further, logs which are part of the blocks on the new chain are emitted, meaning that it is possible to see logs for the same transaction multiple times in the case of a reorganization.

Parameters is an object with the following fields: adddress (optional): either a string representing an address or an array of such strings.Only logs created from one of these addresses will be emitted. topics: an array of topic specifiers. Each topic specifier is either null, a string representing a topic, or an array of strings.Each position in the array which is not null restricts the emitted logs to only those who have one of the given topics in that position. Some examples of topic specifications: []: Any topics allowed. [A]: A in first position (and anything after). [null, B]: Anything in first position and B in second position (and anything after). [A, B]: A in first position and B in second position (and anything after). [[A, B], [A, B]]: (A or B) in first position and (A or B) in second position (and anything after).

func (*Client) SubscribeNewHeads added in v0.1.2 

func (c *Client) SubscribeNewHeads(callback func(b *web3.Block)) (func() error, error)

Emits an event any time a new header is added to the chain, including during a chain reorganization. When a chain reorganization occurs, this subscription will emit an event containing all new headers for the new chain. In particular, this means that you may see multiple headers emitted with the same height, and when this happens the later header should be taken as the correct one after a reorganization.
