Types

type NoopTxResultCache 

type NoopTxResultCache struct{}

NoopTxResultCache is a no-op implementation of the TxResultCache interface.

func NewNoopTxResultCache 

func NewNoopTxResultCache() *NoopTxResultCache

NewNoopTxResultCache creates a new no-op implementation of the TxResultCache interface.

func (*NoopTxResultCache) Add 

func (n *NoopTxResultCache) Add(flow.Identifier, *accessmodel.TransactionResult) bool

Add adds a transaction result to the cache keyed by its transaction ID, and returns true if an entry was evicted in the process.

This is a no-op implementation which simply ignores the inputs and returns false.

func (*NoopTxResultCache) Get 

func (n *NoopTxResultCache) Get(flow.Identifier) (*accessmodel.TransactionResult, bool)

Get retrieves a cached transaction result by transaction ID, returns true if it exists in the cache, otherwise false.

This is a no-op implementation and always returns nil and false

type Params 

type Params struct {
	Log                          zerolog.Logger

}

type Transactions 

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

func NewTransactionsBackend 

func NewTransactionsBackend(params Params) (*Transactions, error)

func (*Transactions) GetScheduledTransaction 

func (t *Transactions) GetScheduledTransaction(ctx context.Context, scheduledTxID uint64) (*flow.TransactionBody, error)

GetScheduledTransaction returns the transaction body of the scheduled transaction by ID.

Expected error returns during normal operation:

func (*Transactions) GetScheduledTransactionResult 

func (t *Transactions) GetScheduledTransactionResult(ctx context.Context, scheduledTxID uint64, encodingVersion entities.EventEncodingVersion) (*accessmodel.TransactionResult, error)

GetScheduledTransactionResult returns the transaction result of the scheduled transaction by ID.

Expected error returns during normal operation:

func (*Transactions) GetSystemTransaction 

func (t *Transactions) GetSystemTransaction(
	ctx context.Context,
	txID flow.Identifier,
	blockID flow.Identifier,
) (*flow.TransactionBody, error)

GetSystemTransaction returns a system transaction by ID. If no transaction ID is provided, the last system transaction is queried. Note: this function only returns privileged system transactions. It does NOT return user scheduled transactions, which are also contained within the system collection.

func (*Transactions) GetSystemTransactionResult 

func (t *Transactions) GetSystemTransactionResult(
	ctx context.Context,
	txID flow.Identifier,
	blockID flow.Identifier,
	encodingVersion entities.EventEncodingVersion,
) (*accessmodel.TransactionResult, error)

GetSystemTransactionResult returns a system transaction result by ID. If no transaction ID is provided, the last system transaction is queried. Note: this function only returns privileged system transactions. It does NOT return user scheduled transactions, which are also contained within the system collection.

func (*Transactions) GetTransaction 

func (t *Transactions) GetTransaction(ctx context.Context, txID flow.Identifier) (*flow.TransactionBody, error)

func (*Transactions) GetTransactionResult 

func (t *Transactions) GetTransactionResult(
	ctx context.Context,
	txID flow.Identifier,
	blockID flow.Identifier,
	collectionID flow.Identifier,
	encodingVersion entities.EventEncodingVersion,
) (txResult *accessmodel.TransactionResult, err error)

func (*Transactions) GetTransactionResultByIndex 

func (t *Transactions) GetTransactionResultByIndex(
	ctx context.Context,
	blockID flow.Identifier,
	index uint32,
	encodingVersion entities.EventEncodingVersion,
) (*accessmodel.TransactionResult, error)

GetTransactionResultByIndex returns transactions Results for an index in a block that is executed, pending or finalized transactions return errors

func (*Transactions) GetTransactionResultsByBlockID 

func (t *Transactions) GetTransactionResultsByBlockID(
	ctx context.Context,
	blockID flow.Identifier,
	encodingVersion entities.EventEncodingVersion,
) ([]*accessmodel.TransactionResult, error)

func (*Transactions) GetTransactionsByBlockID 

func (t *Transactions) GetTransactionsByBlockID(
	ctx context.Context,
	blockID flow.Identifier,
) ([]*flow.TransactionBody, error)

func (*Transactions) SendRawTransaction 

func (t *Transactions) SendRawTransaction(
	ctx context.Context,
	tx *flow.TransactionBody,
) error

SendRawTransaction sends a raw transaction to the collection node

func (*Transactions) SendTransaction 

func (t *Transactions) SendTransaction(ctx context.Context, tx *flow.TransactionBody) error

SendTransaction forwards the transaction to the collection node

type TxResultCache 

type TxResultCache interface {
	// Get retrieves a cached transaction result by transaction ID,	returns true if it exists in the
	// cache, otherwise false.
	Get(flow.Identifier) (*accessmodel.TransactionResult, bool)

	// Add adds a transaction result to the cache keyed by its transaction ID, and returns true if
	// an entry was evicted in the process.
	Add(flow.Identifier, *accessmodel.TransactionResult) bool
}

TxResultCache is a cache for transaction results used by the API to avoid unnecessary lookups on historical access nodes.
