func IntContains

func IntContains(target []int, src int) bool

func IntToString

func IntToString(orig []int8) string

func IsContainerized

func IsContainerized() (bool, error)

func ParseFloat

func ParseFloat(s string) float64

func ParseUint64

func ParseUint64(s string) uint64

func PathExists

func PathExists(filename string) bool

func PathExistsWithContents

func PathExistsWithContents(filename string) bool

func ReadFile

func ReadFile(filename string) (string, error)

func ReadFileNoStat

func ReadFileNoStat(filename string) ([]byte, error)

ReadFileNoStat uses ioutil.ReadAll to read contents of entire file. This is similar to ioutil.ReadFile but without the call to os.Stat, because many files in /proc and /sys report incorrect file sizes (either 0 or 4096). Reads a max file size of 512kB. For files larger than this, a scanner should be used.

func ReadInts

func ReadInts(filename string) ([]int64, error)

func ReadLine

func ReadLine(filename string, prefix string) (string, error)

ReadLine reads a file and returns the first occurrence of a line that is prefixed with prefix.

func ReadLines

func ReadLines(filename string) ([]string, error)

func ReadLinesOffsetN

func ReadLinesOffsetN(filename string, offset uint, n int) ([]string, error)

ReadLinesOffsetN reads contents from file and splits them by new line. The offset tells at which line number to start. The count determines the number of lines to read (starting from offset): n >= 0: at most n lines n < 0: whole file

func Round

func Round(val float64, n int) float64

func Sleep

func Sleep(ctx context.Context, interval time.Duration) error

func StringsContains

func StringsContains(target []string, src string) bool

func StringsHas

func StringsHas(target []string, src string) bool

func UintToString

func UintToString(orig []uint8) string
