Types

type And

type And []Filter

func (And) Apply

func (a And) Apply(tx *tx.Tx, columns *rows.Row) (*rows.Row, error)

type Filter

type Filter interface {
	Apply(tx *tx.Tx, columns *rows.Row) (*rows.Row, error)
}

Filter selects rows to read in a shard/view context.

type IDs

type IDs []uint64

IDs is a query return type for just uint64 row ids. It should only be used internally (since RowIdentifiers is the external return type), but it is exported because the proto package needs access to it.

func (IDs) Merge

func (r IDs) Merge(other IDs, limit int) IDs

type Noop

type Noop struct{}

func (Noop) Apply

func (Noop) Apply(tx *tx.Tx, columns *rows.Row) (*rows.Row, error)

type Or

type Or []Filter

func (Or) Apply

func (a Or) Apply(tx *tx.Tx, columns *rows.Row) (*rows.Row, error)

type RowIterator

type RowIterator interface {
	io.Seeker
	Next() (*rows.Row, uint64, *int64, bool, error)
}
