Functions

func ApplyRangeToHttpHeader

func ApplyRangeToHttpHeader(p Range, headerRef http.Header) http.Header

ApplyRangeToHttpHeader for http request header

func ParseContentRange

func ParseContentRange(s string) (start, end int64, err error)

ParseContentRange this function parse content-range in http response

Types

type Range

type Range struct {
	Start  int64
	Length int64 // limit of bytes to read, -1 for unlimited
}

Range specifies the byte range to be sent to the client.

func ParseRange

func ParseRange(s string, size int64) ([]Range, error)

ParseRange parses a Range header string as per RFC 7233. ErrNoOverlap is returned if none of the ranges overlap. ErrInvalid is returned if s is invalid range.

func (Range) ContentRange

func (r Range) ContentRange(size int64) string

ContentRange returns Content-Range header value.

func (Range) MimeHeader

func (r Range) MimeHeader(contentType string, size int64) textproto.MIMEHeader
