Types

type ColumnDef

type ColumnDef struct {
	Name     string `json:"name"`
	DataType string `json:"data_type"`
	// contains filtered or unexported fields
}

ColumnDef is a struct used to store column information from query results

func (*ColumnDef) IsScalar

func (c *ColumnDef) IsScalar(v any) bool

IsScalar checks if the given value is a scalar value it also mutates the containing ColumnDef so that it doesn't have to reflect for all values in a column

type Result

type Result struct {
	RowChan      *chan *RowResult
	Cols         []*ColumnDef
	TimingResult chan *TimingResult
}

func NewResult

func NewResult(cols []*ColumnDef) *Result

func (*Result) Close

func (r *Result) Close()

Close closes the row channel

func (*Result) IsExportSourceData

func (*Result) IsExportSourceData()

IsExportSourceData implements ExportSourceData

func (*Result) StreamError

func (r *Result) StreamError(err error)

func (*Result) StreamRow

func (r *Result) StreamRow(rowResult []interface{})

type ResultStreamer

type ResultStreamer struct {
	Results chan *Result
	// contains filtered or unexported fields
}

func NewResultStreamer

func NewResultStreamer() *ResultStreamer

func (*ResultStreamer) AllResultsRead

func (q *ResultStreamer) AllResultsRead()

AllResultsRead is a signal that indicates the all results have been read from the stream

func (*ResultStreamer) Close

func (q *ResultStreamer) Close()

Close closes the result stream

func (*ResultStreamer) StreamResult

func (q *ResultStreamer) StreamResult(result *Result)

StreamResult streams result on the Results channel, then waits for them to be read

type RowResult

type RowResult struct {
	Data  []interface{}
	Error error
}

type SyncQueryResult

type SyncQueryResult struct {
	Rows         []interface{}
	Cols         []*ColumnDef
	TimingResult *TimingResult
}

type TimingMetadata

type TimingMetadata struct {
	RowsFetched       int64
	CachedRowsFetched int64
	HydrateCalls      int64
}

type TimingResult

type TimingResult struct {
	Duration time.Duration
	Metadata *TimingMetadata
}
