Types ¶

type CSVPrinter ¶

type CSVPrinter struct {
	Filename string
	// contains filtered or unexported fields
}

CSVPrinter prints ledger entries to a file or stdout (when Filename is empty). Can be used both for processing state and ledgers. The state output matches the format of data in diamnet-core DB so can be used for diff-testing the state readers.

func (*CSVPrinter) Name ¶

func (p *CSVPrinter) Name() string

func (*CSVPrinter) ProcessLedger ¶

func (p *CSVPrinter) ProcessLedger(ctx context.Context, store *pipeline.Store, r io.LedgerReader, w io.LedgerWriter) error

func (*CSVPrinter) ProcessState ¶

func (p *CSVPrinter) ProcessState(ctx context.Context, store *pipeline.Store, r io.StateReader, w io.StateWriter) error

func (*CSVPrinter) Reset ¶

func (n *CSVPrinter) Reset()

type EntryTypeFilter ¶

type EntryTypeFilter struct {
	Type xdr.LedgerEntryType
	// contains filtered or unexported fields
}

EntryTypeFilter is a pipeline.StateProcessor that filters out all entries that are not of type `Type`.

func (*EntryTypeFilter) Name ¶

func (p *EntryTypeFilter) Name() string

func (*EntryTypeFilter) ProcessState ¶

func (p *EntryTypeFilter) ProcessState(ctx context.Context, store *pipeline.Store, r io.StateReader, w io.StateWriter) error

func (*EntryTypeFilter) Reset ¶

func (n *EntryTypeFilter) Reset()

type RootProcessor ¶

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

RootProcessor is useful when a pipeline needs to be split stream into multiple branches right away. This processor is a no-op - just passes the data to all children.

func (*RootProcessor) Name ¶

func (p *RootProcessor) Name() string

func (*RootProcessor) ProcessLedger ¶

func (p *RootProcessor) ProcessLedger(ctx context.Context, store *pipeline.Store, r io.LedgerReader, w io.LedgerWriter) error

func (*RootProcessor) ProcessState ¶

func (p *RootProcessor) ProcessState(ctx context.Context, store *pipeline.Store, r io.StateReader, w io.StateWriter) error

func (*RootProcessor) Reset ¶

func (n *RootProcessor) Reset()

type StatusLogger ¶

type StatusLogger struct {
	N int
	// contains filtered or unexported fields
}

StatusLogger prints number of processed entries every N entries.

func (*StatusLogger) Name ¶

func (p *StatusLogger) Name() string

func (*StatusLogger) ProcessState ¶

func (p *StatusLogger) ProcessState(ctx context.Context, store *pipeline.Store, r io.StateReader, w io.StateWriter) error

func (*StatusLogger) Reset ¶

func (n *StatusLogger) Reset()
