Types ¶
type AccountInfo ¶
type AccountInfo struct {
Changes [][2]uint64 `json:"changes"`
Proxy bool `json:"proxy,omitempty"`
}
AccountInfo represents all the balance changes (block height, balance) for an account and whether it's a proxy account or not.
type BalanceData ¶
BalanceData represents the indexed balance of an account.
type BlockData ¶
type BlockData struct {
Block *model.IndexedBlock
Hash []byte
Height uint64
ParentHash []byte
ParentHeight uint64
}
BlockData represents the indexed data for a block.
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store aggregates the blockchain data for Rosetta API calls.
func (*Store) Accounts ¶
Accounts returns the addresses of all our indexed accounts, and whether the account is a proxy account or not.
func (*Store) AccountsInfo ¶
func (s *Store) AccountsInfo() (map[string]*AccountInfo, error)
AccountsInfo will return a map of the indexed accounts and their corresponding account info.
func (*Store) BalanceByHash ¶
func (s *Store) BalanceByHash(acct []byte, hash []byte) (*BalanceData, error)
BalanceByHash returns the account balance at the given hash.
func (*Store) BalanceByHeight ¶
func (s *Store) BalanceByHeight(acct []byte, height uint64) (*BalanceData, error)
BalanceByHeight returns the account balance at the given height.
func (*Store) BlockByHash ¶
BlockByHash returns the block data for the given hash.
func (*Store) BlockByHeight ¶
BlockByHeight returns the block data for the given height.
func (*Store) ExportAccounts ¶
ExportAccounts will export a map of the indexed accounts and their corresponding account info.
func (*Store) HasBalance ¶
HasBalance returns whether the given account has an indexed balance at the given height.
func (*Store) HashForHeight ¶
HashForHeight returns the block hash at the given height.
func (*Store) HeightForHash ¶
HeightForHash returns the block height for the given hash.
func (*Store) Index ¶
func (s *Store) Index(ctx context.Context, height uint64, hash []byte, block *model.IndexedBlock) error
Index indexes the given block data.
func (*Store) PurgeProxyAccounts ¶
func (s *Store) PurgeProxyAccounts()
PurgeProxyAccounts removes any indexed account balances or proxy account creation heights from the index database.
