Types

type Client 

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

Client defines typed wrappers for the Ethereum RPC API.

Dial connects a client to the given URL.

func DialContext 

func DialContext(ctx context.Context, rawurl string) (*Client, error)

func NewClient 

func NewClient(c *rpc.Client) *Client

NewClient creates a client that uses the given RPC client.

func (*Client) AllInfoByAddress 

func (ec *Client) AllInfoByAddress(ctx context.Context, address common.Address, blockNr *big.Int) (*common.AllInfoForAddress, error)

func (*Client) AllTickets 

func (ec *Client) AllTickets(ctx context.Context, blockNr *big.Int) (map[common.Hash]common.TicketDisplay, error)

func (*Client) AllTicketsByAddress 

func (ec *Client) AllTicketsByAddress(ctx context.Context, address common.Address, blockNr *big.Int) (map[common.Hash]common.TicketDisplay, error)

func (*Client) BalanceAt 

func (ec *Client) BalanceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (*big.Int, error)

BalanceAt returns the wei balance of the given account. The block number can be nil, in which case the balance is taken from the latest known block.

func (*Client) BlockByHash 

func (ec *Client) BlockByHash(ctx context.Context, hash common.Hash) (*types.Block, error)

BlockByHash returns the given full block.

Note that loading full blocks requires two requests. Use HeaderByHash if you don't need all transactions or uncle headers.

func (*Client) BlockByNumber 

func (ec *Client) BlockByNumber(ctx context.Context, number *big.Int) (*types.Block, error)

BlockByNumber returns a block from the current canonical chain. If number is nil, the latest known block is returned.

Note that loading full blocks requires two requests. Use HeaderByNumber if you don't need all transactions or uncle headers.

func (*Client) CallContract 

func (ec *Client) CallContract(ctx context.Context, msg ethereum.CallMsg, blockNumber *big.Int) ([]byte, error)

CallContract executes a message call transaction, which is directly executed in the VM of the node, but never mined into the blockchain.

blockNumber selects the block height at which the call runs. It can be nil, in which case the code is taken from the latest known block. Note that state from very old blocks might not be available.

func (*Client) Close 

func (ec *Client) Close()

func (*Client) CodeAt 

func (ec *Client) CodeAt(ctx context.Context, account common.Address, blockNumber *big.Int) ([]byte, error)

func (*Client) EstimateGas 

func (ec *Client) EstimateGas(ctx context.Context, msg ethereum.CallMsg) (uint64, error)
