Functions ¶
func ByteSize ¶
ByteSize returns a human-readable byte string of the form 10M, 12.5K, and so forth. The following units are available:
E: Exabyte P: Petabyte T: Terabyte G: Gigabyte M: Megabyte K: Kilobyte B: Byte
The unit that results in the smallest number greater than or equal to 1 is always chosen.
func ClearRange ¶
func ReadRegion ¶
func ToBytes ¶
ToBytes parses a string formatted by ByteSize as bytes. Note binary-prefixed and SI prefixed units both mean a base-2 units KB = K = KiB = 1024 MB = M = MiB = 1024 * K GB = G = GiB = 1024 * M TB = T = TiB = 1024 * G PB = P = PiB = 1024 * T EB = E = EiB = 1024 * P
func ToMegabytes ¶
ToMegabytes parses a string formatted by ByteSize as megabytes.
Types ¶
type File ¶
type File struct {
// contains filtered or unexported fields
}
func (*File) ReadRegion ¶
func (f *File) ReadRegion(offset int64, capacity int64) (region FileRegion, err error)
type FileRegion ¶
type FileRegion interface {
io.ReaderAt
io.ReadCloser
Bytes() (p []byte)
}
