func NumProcs 

func NumProcs() (uint64, error)

func NumProcsWithContext 

func NumProcsWithContext(ctx context.Context) (uint64, error)

func PathExists 

func PathExists(filename string) bool

func PathExistsWithContents 

func PathExistsWithContents(filename string) bool

PathExistsWithContents returns the filename exists and it is not empty

func Read 

func Read(r io.Reader, order ByteOrder, data interface{}) error

Read reads structured binary data from r into data. Data must be a pointer to a fixed-size value or a slice of fixed-size values. Bytes read from r are decoded using the specified byte order and written to successive fields of the data. When reading into structs, the field data for fields with blank (_) field names is skipped; i.e., blank field names may be used for padding. When reading into a struct, all non-blank fields must be exported.

func ReadFile 

func ReadFile(filename string) (string, error)

ReadFile reads contents from a file

func ReadInts 

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

ReadInts reads contents from single line file and returns them as []int32.

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)

ReadLines reads contents from a file and splits them by new lines. A convenience wrapper to ReadLinesOffsetN(filename, 0, -1).

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 added in v4.24.7 

func Round(val float64, n int) float64

Round places rounds the number 'val' to 'n' decimal places

func Size 

func Size(v interface{}) int

Size returns how many bytes Write would generate to encode the value v, which must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. If v is neither of these, Size returns -1.

func Sleep 

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

Sleep awaits for provided interval. Can be interrupted by context cancellation.

func StringsContains 

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

StringsContains checks the src in any string of the target string slice

func StringsHas 

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

StringsHas checks the target string slice contains src or not

func UintToString 

func UintToString(orig []uint8) string

func Virtualization 

func Virtualization() (string, string, error)

func VirtualizationWithContext 

func VirtualizationWithContext(ctx context.Context) (string, string, error)

func Write 

func Write(w io.Writer, order ByteOrder, data interface{}) error

Write writes the binary representation of data into w. Data must be a fixed-size value or a slice of fixed-size values, or a pointer to such data. Bytes written to w are encoded using the specified byte order and read from successive fields of the data. When writing structs, zero values are written for fields with blank (_) field names.

Types

type ByteOrder 

type ByteOrder interface {
	Uint16([]byte) uint16
	Uint32([]byte) uint32
