funcFormatContentRange¶

func FormatContentRange(start, length, completeLengthint64) (hdrstring, okbool)

FormatContentRange parses a "Content-Range" header perRFC 7233, section 4.2.It only handles "Content-Range" headers where the units is "bytes".The "Content-Range" header is usually only specified in HTTP responses.

If start and length are non-positive, then it encodes just the completeLength,which must be a non-negative value.

Otherwise, it encodes the start and length as a byte-range,and optionally emits the complete length if it is non-negative.The length must be positive (asRFC 7233 uses inclusive end offsets).

funcFormatRange¶

func FormatRange(ranges []Range) (hdrstring, okbool)

FormatRange formats a "Range" header perRFC 7233, section 3.It only handles "Range" headers where the units is "bytes".The "Range" header is usually only specified in GET requests.

funcParseContentRange¶

func ParseContentRange(hdrstring) (start, length, completeLengthint64, okbool)

ParseContentRange parses a "Content-Range" header perRFC 7233, section 4.2.It only handles "Content-Range" headers where the units is "bytes".The "Content-Range" header is usually only specified in HTTP responses.

If only the completeLength is specified, then start and length are both zero.

Otherwise, the parses the start and length and the optional completeLength,which is -1 if unspecified. The start is non-negative and the length is positive.

typeRange¶

type Range struct {// Start is the starting offset.// It is zero if Length is negative; it must not be negative.Startint64// Length is the length of the content.// It is zero if the length extends to the end of the content.// It is negative if the length is relative to the end (e.g., last 5 bytes).Lengthint64}

Range is a range of bytes within some content.
