Functions

func ParseString

func ParseString(str string) (uint64, error)

ParseString

@param str 同时支持"IEC标准"和"SI标准" @return 第一个返回值的单位: 字节(bytes)

e.g. ("42MB") => 42000000 <nil> ("42 MB") => 42000000 <nil> ("42mib") => 44040192 <nil> ("42 mib") => 44040192 <nil>

func ToReadableStringWithIEC

func ToReadableStringWithIEC(s uint64) string

ToReadableStringWithIEC

PS: (1) 采用IEC标准（国际电工委员会；https://blog.csdn.net/bioitee/article/details/120797739）. (2) 1KB == 1024 (3) 采用此标准: Windows的文件资源管理器、钉钉（Mac版和Windows版都是）、XManager和Tabby的可视化工具...

@param s 单位: 字节(bytes)

e.g.

(78848) => "77 KiB"

func ToReadableStringWithSI

func ToReadableStringWithSI(s uint64) string

ToReadableStringWithSI

PS: (1) 采用SI标准（国际单位制；https://blog.csdn.net/bioitee/article/details/120797739）. (2) 1KB == 1000 (3) 采用此标准: Mac的访达...

@param s 单位: 字节(bytes)

e.g.

(78848) => "79 kB"

Types

type DataSize

type DataSize struct {
	// 数值
	Number float64
	// 单位
	Unit *Unit
}

func (*DataSize) ConvertToTargetUint

func (size *DataSize) ConvertToTargetUint(targetUnit *Unit) *DataSize

ConvertToTargetUint 单位转换

@param targetUnit 可以为nil，将使用默认单位

func (*DataSize) GetByteValue

func (size *DataSize) GetByteValue() uint64

GetByteValue

@return 单位: B(byte)

func (*DataSize) ToString

func (size *DataSize) ToString(precArgs ...int) string

ToString

@param args 默认（不传参）不对小数位进行处理

func (*DataSize) ToSuitableUint

func (size *DataSize) ToSuitableUint() *DataSize

type Unit

type Unit struct {
	// contains filtered or unexported fields
}

func (*Unit) GetValue

func (su *Unit) GetValue() uint64

func (*Unit) String

func (su *Unit) String() string
