Types

type AccountResult

type AccountResult struct {
	Address      common.Address  `json:"address"`
	AccountProof []string        `json:"accountProof"`
	Balance      *big.Int        `json:"balance"`
	CodeHash     common.Hash     `json:"codeHash"`
	Nonce        uint64          `json:"nonce"`
	StorageHash  common.Hash     `json:"storageHash"`
	StorageProof []StorageResult `json:"storageProof"`
}

AccountResult is the result of a GetProof operation.

type Client

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

Client is a wrapper around rpc.Client that implements gbina-specific functionality.

If you want to use the standardized Binacoin RPC functionality, use bnaclient.Client instead.

func New

func New(c *rpc.Client) *Client

New creates a client that uses the given RPC client.

func (*Client) CallContract

func (ec *Client) CallContract(ctx context.Context, msg binacoin.CallMsg, blockNumber *big.Int, overrides *map[common.Address]OverrideAccount) ([]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.

overrides specifies a map of contract states that should be overwritten before executing the message call. Please use bnaclient.CallContract instead if you don't need the override functionality.

func (*Client) CreateAccessList

func (ec *Client) CreateAccessList(ctx context.Context, msg binacoin.CallMsg) (*types.AccessList, uint64, string, error)

CreateAccessList tries to create an access list for a specific transaction based on the current pending state of the blockchain.

func (*Client) GCStats

func (ec *Client) GCStats(ctx context.Context) (*debug.GCStats, error)

GCStats retrieves the current garbage collection stats from a gbina node.

func (*Client) GetNodeInfo

func (ec *Client) GetNodeInfo(ctx context.Context) (*p2p.NodeInfo, error)

GetNodeInfo retrieves the node info of a gbina node.

func (*Client) GetProof

func (ec *Client) GetProof(ctx context.Context, account common.Address, keys []string, blockNumber *big.Int) (*AccountResult, error)

GetProof returns the account and storage values of the specified account including the Merkle-proof. The block number can be nil, in which case the value is taken from the latest known block.

func (*Client) MemStats

func (ec *Client) MemStats(ctx context.Context) (*runtime.MemStats, error)

MemStats retrieves the current memory stats from a gbina node.

func (*Client) SetHead

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

SetHead sets the current head of the local chain by block number. Note, this is a destructive action and may severely damage your chain. Use with extreme caution.

func (*Client) SubscribePendingTransactions

func (ec *Client) SubscribePendingTransactions(ctx context.Context, ch chan<- common.Hash) (*rpc.ClientSubscription, error)

SubscribePendingTransactions subscribes to new pending transactions.

type OverrideAccount

type OverrideAccount struct {
	Nonce     uint64                      `json:"nonce"`
	Code      []byte                      `json:"code"`
	Balance   *big.Int                    `json:"balance"`
	State     map[common.Hash]common.Hash `json:"state"`
	StateDiff map[common.Hash]common.Hash `json:"stateDiff"`
}

OverrideAccount specifies the state of an account to be overridden.

type StorageResult

type StorageResult struct {
	Key   string   `json:"key"`
	Value *big.Int `json:"value"`
	Proof []string `json:"proof"`
}

StorageResult provides a proof for a key-value pair.
