Types ¶
type Database ¶
type Database interface {
WriteBlock(context.Context, *enode.Node, *types.Block)
WriteBlockHeaders(context.Context, []*types.Header)
WriteBlockHashes(context.Context, *enode.Node, []common.Hash)
WriteBlockBody(context.Context, *eth.BlockBody, common.Hash)
WriteTransactions(context.Context, *enode.Node, []*types.Transaction)
HasParentBlock(context.Context, common.Hash) bool
MaxConcurrentWrites() int
ShouldWriteBlocks() bool
ShouldWriteTransactions() bool
}
Database represents a database solution to write block and transaction data to. To use another database solution, just implement these methods and update the sensor to use the new connection.
func NewDatastore ¶
func NewDatastore(ctx context.Context, projectID string, sensorID string, maxConcurrentWrites int, shouldWriteBlocks bool, shouldWriteTransactions bool) Database
NewDatastore connects to datastore and creates the client. This should only be called once unless trying to write to different databases.
type DatastoreBlock ¶
type DatastoreBlock struct {
*DatastoreHeader
Transactions []*datastore.Key
Uncles []*datastore.Key
}
DatastoreBlock represents a block stored in datastore.
type DatastoreEvent ¶
DatastoreEvent can represent a peer sending the sensor a transaction hash or a block hash. In this implementation, the block and transactions are written to different tables by specifying a kind during key creation see writeEvents for more.
type DatastoreHeader ¶
type DatastoreHeader struct {
ParentHash *datastore.Key
UncleHash string
Coinbase string
Root string
TxHash string
ReceiptHash string
Bloom []byte
Difficulty string
Number string
GasLimit string
GasUsed string
Time time.Time
Extra []byte
MixDigest string
Nonce string
BaseFee string
}
DatastoreHeader stores the data in manner that can be easily written without loss of precision.
type DatastoreTransaction ¶
type DatastoreTransaction struct {
Data []byte `datastore:",noindex"`
From string
Gas string
GasFeeCap string
GasPrice string
GasTipCap string
Nonce string
To string
Value string
V, R, S string
Time time.Time
Type int16
}
DatastoreTransaction represents a transaction stored in datastore. Data is not indexed because there is a max sized for indexed byte slices, which Data will occasionally exceed.
