type BlockGenerationInfo struct {
	ProposerIndex uint64
	View          uint64
	Term          uint64
	Proposer      common.Address

	Proposers     []common.Address
}

type BlockNumber 

type BlockNumber struct {
	Number string
}

type Client 

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

Client defines typed wrappers for the Ethereum RPC API.

func Dial 

func Dial(rawurl string) (*Client, error)

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) BalanceAt 

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

func (*Client) BlockByHash 

func (c *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 (c *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 (c *Client) CallContract(ctx context.Context, msg cpchain.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) Campaign 

func (c *Client) Campaign(ctx context.Context, terms uint64) error

func (*Client) ChainConfig

func (*Client) EstimateGas 

func (c *Client) EstimateGas(ctx context.Context, msg cpchain.CallMsg) (uint64, error)

EstimateGas tries to estimate the gas needed to execute a specific transaction based on the current pending state of the backend blockchain. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default.

HeaderByHash returns the block header with the given hash.

func (*Client) HeaderByNumber 

func (c *Client) HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)

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

func (*Client) NetworkID 

func (c *Client) NetworkID(ctx context.Context) (*big.Int, error)

NetworkID returns the network ID (also known as the chain ID) for this chain.

func (*Client) NonceAt 

func (c *Client) NonceAt(ctx context.Context, account common.Address, blockNumber *big.Int) (uint64, error)
