Functions

func RevertErrorData added in v1.10.60 

func RevertErrorData(err error) ([]byte, bool)

Types

type Client 

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

Client defines typed wrappers for the Cortex 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 (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) BalanceAtHash added in v1.10.50 

func (ec *Client) BalanceAtHash(ctx context.Context, account common.Address, blockHash common.Hash) (*big.Int, error)

BalanceAtHash returns the wei balance of the given account.

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) BlockNumber added in v1.10.12 

func (ec *Client) BlockNumber(ctx context.Context) (uint64, error)

BlockNumber returns the most recent block number

func (*Client) CallContract 

func (ec *Client) CallContract(ctx context.Context, msg cortex.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) CallContractAtHash added in v1.10.31 

func (ec *Client) CallContractAtHash(ctx context.Context, msg cortex.CallMsg, blockHash common.Hash) ([]byte, error)

CallContractAtHash is almost the same as CallContract except that it selects the block by block hash instead of block height.

func (*Client) ChainID added in v1.10.3 

func (ec *Client) ChainID(ctx context.Context) (*big.Int, error)

ChainId retrieves the current chain ID for transaction replay protection.

func (*Client) Client added in v1.10.43 

func (ec *Client) Client() *rpc.Client

Client gets the underlying RPC client.

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)

CodeAt returns the contract code of the given account. The block number can be nil, in which case the code is taken from the latest known block.

func (*Client) EstimateGas 

func (ec *Client) EstimateGas(ctx context.Context, msg cortex.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.

func (*Client) FilterLogs 

func (ec *Client) FilterLogs(ctx context.Context, q cortex.FilterQuery) ([]types.Log, error)

FilterLogs executes a filter query.

func (*Client) HeaderByHash 

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

HeaderByHash returns the block header with the given hash.

func (*Client) HeaderByNumber 

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

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

func (*Client) PeerCount added in v1.10.31 

func (ec *Client) PeerCount(ctx context.Context) (uint64, error)

PeerCount returns the number of p2p peers as reported by the net_peerCount method.

func (*Client) PendingBalanceAt 

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

PendingBalanceAt returns the wei balance of the given account in the pending state.

func (*Client) PendingCallContract 

func (ec *Client) PendingCallContract(ctx context.Context, msg cortex.CallMsg) ([]byte, error)

PendingCallContract executes a message call transaction using the CVM. The state seen by the contract call is the pending state.

func (*Client) PendingCodeAt 

func (ec *Client) PendingCodeAt(ctx context.Context, account common.Address) ([]byte, error)

PendingCodeAt returns the contract code of the given account in the pending state.

func (*Client) PendingNonceAt 

func (ec *Client) PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)

PendingNonceAt returns the account nonce of the given account in the pending state. This is the nonce that should be used for the next transaction.

func (*Client) PendingStorageAt 

func (ec *Client) PendingStorageAt(ctx context.Context, account common.Address, key common.Hash) ([]byte, error)

PendingStorageAt returns the value of key in the contract storage of the given account in the pending state.

func (*Client) SendTransaction 

func (ec *Client) SendTransaction(ctx context.Context, tx *types.Transaction) error

SendTransaction injects a signed transaction into the pending pool for execution.

If the transaction was a contract creation use the TransactionReceipt method to get the contract address after the transaction has been mined.

func (*Client) StorageAt 

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

StorageAt returns the value of key in the contract storage of the given account. The block number can be nil, in which case the value is taken from the latest known block.

func (*Client) SubscribeFilterLogs 

func (ec *Client) SubscribeFilterLogs(ctx context.Context, q cortex.FilterQuery, ch chan<- types.Log) (cortex.Subscription, error)

SubscribeFilterLogs subscribes to the results of a streaming filter query.

func (*Client) SubscribeNewHead 

func (ec *Client) SubscribeNewHead(ctx context.Context, ch chan<- *types.Header) (cortex.Subscription, error)

SubscribeNewHead subscribes to notifications about the current blockchain head on the given channel.

func (*Client) SuggestGasPrice 

func (ec *Client) SuggestGasPrice(ctx context.Context) (*big.Int, error)

SuggestGasPrice retrieves the currently suggested gas price to allow a timely execution of a transaction.

func (*Client) SyncProgress 

func (ec *Client) SyncProgress(ctx context.Context) (*cortex.SyncProgress, error)

SyncProgress retrieves the current progress of the sync algorithm. If there's no sync currently running, it returns nil.

func (*Client) TransactionReceipt 

func (ec *Client) TransactionReceipt(ctx context.Context, txHash common.Hash) (*types.Receipt, error)
