Functions ¶

func IsZeroFilled ¶

func IsZeroFilled(b []byte) bool

IsZeroFilled returns true if b consists of zeros only.

Types ¶

type Range ¶

type Range struct {
	Offset uint64
	Length uint64
}

Range defines is a generic bytes range headers.

func (Range) End ¶

func (r Range) End() uint64

End returns the first offset after the range.

func (Range) Exclude ¶

func (r Range) Exclude(_toExcludes ...Range) Ranges

Exclude returns the parts of the range, which excludes the selected ones.

func (Range) Intersect ¶

func (r Range) Intersect(cmp Range) bool

Intersect returns True if ranges "r" and "cmp" has at least one byte with the same offset.

func (Range) String ¶

func (r Range) String() string

type Ranges ¶

type Ranges []Range

Ranges is a helper to manipulate multiple `Range`-s at once

func MergeRanges ¶

func MergeRanges(in Ranges, mergeDistance uint64) Ranges

MergeRanges just merges ranges which has distance less or equal to mergeDistance.

Warning: should be called only on sorted ranges!

func (Ranges) Compile ¶

func (s Ranges) Compile(b []byte) []byte

Compile returns the bytes from `b` which are referenced by `Range`-s `s`.

func (Ranges) IsIn ¶

func (s Ranges) IsIn(index uint64) bool

IsIn returns if the index is covered by this ranges

func (Ranges) Sort ¶

func (s Ranges) Sort()

Sort sorts the slice by field Offset

func (*Ranges) SortAndMerge ¶

func (s *Ranges) SortAndMerge()

SortAndMerge sorts the slice (by field Offset) and the merges ranges which could be merged.

func (Ranges) String ¶

func (s Ranges) String() string
