var EmptyBlockReader = BlockReader{}

EmptyBlockReader represents the default block reader.

Functions

func FilterEmptyBlockReadersSliceOfSlicesInPlace added in v0.11.0 

func FilterEmptyBlockReadersSliceOfSlicesInPlace(brSliceOfSlices [][]BlockReader) ([][]BlockReader, error)

FilterEmptyBlockReadersSliceOfSlicesInPlace filters a [][]BlockReader in place (I.E by modifying the existing data structures instead of allocating new ones) such that the returned [][]BlockReader will only contain BlockReaders that contain non-empty segments.

Note that if any of the Block/Segment readers are backed by async implementations then this function will not return until all of the async execution has completed.

Types

type BlockReader 

type BlockReader struct {
	SegmentReader
	Start     time.Time
	BlockSize time.Duration
}

BlockReader represents a block reader backed by a SegmentReader with start time and block size.

func FilterEmptyBlockReadersInPlace added in v0.11.0 

func FilterEmptyBlockReadersInPlace(brs []BlockReader) ([]BlockReader, error)

FilterEmptyBlockReadersInPlace is the same as FilterEmptyBlockReadersSliceOfSlicesInPlace except for one dimensional slices instead of two.
