Functions

func FileExists

func FileExists(filename string) bool

FileExists Checks whether a file or directory exists

func IsArray

func IsArray(value interface{}, strict ...bool) bool

IsArray Check if the value is an array, the default is non-strict mode Non-strict mode type is SLICE, Array, and map will return true. Returns True when only the array type

func IsPtr

func IsPtr(value interface{}) bool

IsPtr Check if value is a pointer type

func IsSlice

func IsSlice(value interface{}) bool

IsSlice check if value is slice

func SafeMul

func SafeMul(a, b uint) uint

SafeMul Safety multiplication

func StrSizeToBytes

func StrSizeToBytes(sizeStr string) uint

StrSizeToBytes converts strings like 1GB or 12 mb into an unsigned integer number of bytes

func Typeof

func Typeof(value interface{}) (typ string, kind string)

Typeof return the value data type

func Unmarshal

func Unmarshal(data interface{}, v interface{}) error
