Functions

func ArrContainsStr

func ArrContainsStr(array []string, str string) bool

ArrContainsStr checks if a string is in a string array

func Convert

func Convert[T any](value string, convertor func(string) (T, error), defaultValue ...T) (*T, error)

func ConvertBytesToHumanReadableSize

func ConvertBytesToHumanReadableSize(bytes int) string

ConvertBytesToHumanReadableSize converts the given integer size in bytes to a human-readable string format. If the size is 0, it returns "0B". It uses the logarithmic calculation to determine the appropriate unit prefix (e.g., KB, MB, GB, etc.), and formats the value with two decimal places before appending the unit suffix. The units slice contains the available unit prefixes: ["B", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB"]. Note: The function assumes that the given size is a positive integer.

func CopyIOZeroAlloc

func CopyIOZeroAlloc(w io.Writer, r io.Reader) (int64, error)

func FilePathToIOReader

func FilePathToIOReader(filePath string) (io.Reader, error)

func GenXid

func GenXid() string

func HumanReadableSizeToBytes

func HumanReadableSizeToBytes(humanReadableString string) int

HumanReadableSizeToBytes returns integer size of bytes from human-readable string, ex. 42kb, 42M Returns 0 if string is unrecognized
