Common binary data sizes

Types

type Size

type Size uint64

Size represents the size of data in bytes.

func Flag

func Flag(name, value, description string) *Size

Flag defines a Size flag with specified name, default value, and usage string.

func Parse

func Parse(s string) (Size, error)

Parse parses a Size from a string. A Size is an unsigned decimal number with an optional fraction and a unit suffix. Examples: "0", "10B", "1kB", "4GB", "5GiB". Valid units are "B", (decimal: "kB", "MB", "GB, "TB, "PB"), (binary: "KiB", "MiB", "GiB", "TiB", "PiB")

func (Size) Bytes

func (s Size) Bytes() uint64

Bytes returns s in the equivalent number of bytes.

func (Size) Gibibytes

func (s Size) Gibibytes() float64

Gibibytes returns s in the equivalent number of gibibytes.

func (Size) Gigabytes

func (s Size) Gigabytes() float64

Gigabytes returns s in the equivalent number of gigabytes.

func (Size) Kibibytes

func (s Size) Kibibytes() float64

Kibibytes returns s in the equivalent number of kibibytes.

func (Size) Kilobytes

func (s Size) Kilobytes() float64

Kilobytes returns s in the equivalent number of kilobytes.

func (Size) Mebibytes

func (s Size) Mebibytes() float64

Mebibytes returns s in the equivalent number of mebibytes.

func (Size) Megabytes

func (s Size) Megabytes() float64

Megabytes returns s in the equivalent number of megabytes.

func (Size) Pebibytes

func (s Size) Pebibytes() float64

Pebibytes returns s in the equivalent number of pebibytes.

func (Size) Petabytes

func (s Size) Petabytes() float64

Petabytes returns s in the equivalent number of petabytes.

func (Size) String

func (s Size) String() string

String implements the Stringer interface.

func (Size) Tebibytes

func (s Size) Tebibytes() float64

Tebibytes returns s in the equivalent number of tebibytes.

func (Size) Terabytes

func (s Size) Terabytes() float64

Terabytes returns s in the equivalent number of terabytes.
