Units - Helpful unit multipliers and functions for Go

The goal of this package is to have functionality similar to the time package.

It allows for code like this:

n, err := ParseBase2Bytes("1KB")
// n == 1024
n = units.Mebibyte * 512

Overview

Package units provides helpful unit multipliers and functions for Go.

The goal of this package is to have functionality similar to the time [1] package.

[1] http://golang.org/pkg/time/

It allows for code like this:

n, err := ParseBase2Bytes("1KB")
// n == 1024
n = units.Mebibyte * 512

Functions

func MakeUnitMap

func MakeUnitMap(suffix, shortSuffix string, scale int64) map[string]float64

func ParseStrictBytes

func ParseStrictBytes(s string) (int64, error)

ParseStrictBytes supports both iB and B suffixes for base 2 and metric, respectively. That is, KiB represents 1024 and KB represents 1000.

func ParseUnit

func ParseUnit(s string, unitMap map[string]float64) (int64, error)

func ToString

func ToString(n int64, scale int64, suffix, baseSuffix string) string

Types

type Base2Bytes

type Base2Bytes int64

Base2Bytes is the old non-SI power-of-2 byte scale (1024 bytes in a kilobyte, etc.).

func ParseBase2Bytes

func ParseBase2Bytes(s string) (Base2Bytes, error)

ParseBase2Bytes supports both iB and B in base-2 multipliers. That is, KB and KiB are both 1024.

func (Base2Bytes) String

func (b Base2Bytes) String() string

type MetricBytes

type MetricBytes SI

MetricBytes are SI byte units (1000 bytes in a kilobyte).

func ParseMetricBytes

func ParseMetricBytes(s string) (MetricBytes, error)

ParseMetricBytes parses base-10 metric byte units. That is, KB is 1000 bytes.

func (MetricBytes) String

func (m MetricBytes) String() string

type SI

type SI int64

SI units.
