Types ¶

type BlockRange ¶

type BlockRange FileRange // sugar

type FileRange ¶

type FileRange struct {
	First base.Blknum
	Last  base.Blknum
}

func RangeFromFilename ¶

func RangeFromFilename(path string) (blkRange FileRange)

RangeFromFilename returns a FileRange and ignore any errors

func RangeFromFilenameE ¶

func RangeFromFilenameE(path string) (blkRange FileRange, err error)

RangeFromFilenameE returns a block range given a chunk filename. The format of filenames may be start-end.bin (start and end are nine digit and zero-padded to the left) or start.txt

func RangeFromRangeString ¶

func RangeFromRangeString(rngStr string) FileRange

RangeFromRangeString returns a file range from a string

func (*FileRange) EarlierThan ¶

func (r *FileRange) EarlierThan(needle FileRange) bool

EarlierThan returns true if range is strictly before the given needle range

func (*FileRange) EarlierThanB ¶

func (r *FileRange) EarlierThanB(bn base.Blknum) bool

EarlierThanB returns true if the range is strictly before the given block

func (*FileRange) Equals ¶

func (r *FileRange) Equals(needle FileRange) bool

Equals returns true if the two ranges are equal

func (*FileRange) Follows ¶

func (r *FileRange) Follows(needle FileRange, sequential bool) bool

Follows returns true if the range is strictly after the needle range. (If 'sequential' is true, then the first block in the range must be one more than the last block in the needle range.)

func (*FileRange) Intersects ¶

func (r *FileRange) Intersects(needle FileRange) bool

Intersects returns true if the two ranges intersect

func (*FileRange) IntersectsB ¶

func (r *FileRange) IntersectsB(bn base.Blknum) bool

IntersectsB returns true if the block is inside the range (inclusive on both ends)

func (*FileRange) LaterThan ¶

func (r *FileRange) LaterThan(needle FileRange) bool

LaterThan returns true if range is strictly after the given needle range

func (*FileRange) LaterThanB ¶

func (r *FileRange) LaterThanB(bn base.Blknum) bool

LaterThanB returns true if the range is strictly after the given block

func (*FileRange) Overlaps ¶

func (r *FileRange) Overlaps(test FileRange) (rd RangeDiff)

func (*FileRange) Precedes ¶

func (r *FileRange) Precedes(needle FileRange, sequential bool) bool

Precedes returns true if the range is strictly before the needle range. (If 'sequential' is true, then the last block in the range must be one less than the first block in the needle range.) If the needle range starts at zero, returns false (nothing is before the first range)

func (*FileRange) RangeToFilename ¶

func (r *FileRange) RangeToFilename(chain string) string

RangeToFilename returns a fileName and existence bool given a file range and a type

func (*FileRange) Span ¶

func (r *FileRange) Span() base.Blknum

func (FileRange) String ¶

func (r FileRange) String() string

type RangeDiff ¶

type RangeDiff struct {
	Min base.Blknum
	In  base.Blknum
	Mid base.Blknum
	Out base.Blknum
	Max base.Blknum
}

type RecordRange ¶

type RecordRange struct {
	First uint64
	Last  uint64
}

type TimestampRange ¶

type TimestampRange struct {
	First base.Timestamp
	Last  base.Timestamp
}
