Functions ¶
func IndexRegisterAdapter ¶
func IndexRegisterAdapter(registerFun func(IDs flow.RegisterIDs, height uint64) ([]flow.RegisterValue, error)) func(flow.RegisterID, uint64) (flow.RegisterValue, error)
IndexRegisterAdapter an adapter for using indexer register values function that takes a slice of IDs in the script executor that only uses a single register ID at a time. It also does additional sanity checks if multiple values are returned, which shouldn't occur in normal operation.
Types ¶
type RegistersAtHeight ¶
type RegistersAtHeight func(ID flow.RegisterID, height uint64) (flow.RegisterValue, error)
RegistersAtHeight returns register value for provided register ID at the block height. Even if the register wasn't indexed at the provided height, returns the highest height the register was indexed at. Expected errors: - storage.ErrNotFound if the register by the ID was never indexed - ErrIndexBoundary if the height is out of indexed height boundary
type Scripts ¶
type Scripts struct {
// contains filtered or unexported fields
}
func NewScripts ¶
func NewScripts( log zerolog.Logger, metrics *metrics.ExecutionCollector, chainID flow.ChainID, entropy query.EntropyProviderPerBlock, header storage.Headers, registersAtHeight RegistersAtHeight, ) (*Scripts, error)
func (*Scripts) ExecuteAtBlockHeight ¶
func (s *Scripts) ExecuteAtBlockHeight( ctx context.Context, script []byte, arguments [][]byte, height uint64) ([]byte, error)
ExecuteAtBlockHeight executes provided script against the block height. A result value is returned encoded as byte array. An error will be returned if script doesn't successfully execute. Expected errors: - Storage.NotFound if block or register value at height was not found.
func (*Scripts) GetAccountAtBlockHeight ¶
func (s *Scripts) GetAccountAtBlockHeight(ctx context.Context, address flow.Address, height uint64) (*flow.Account, error)
GetAccountAtBlockHeight returns a Flow account by the provided address and block height. Expected errors: - Storage.NotFound if block or register value at height was not found.
