Functions

func BytesToString

func BytesToString(b []byte) string

BytesToString convert bytes to string Please pay attention to the life cycle of the object when using this function

func CountIntByte

func CountIntByte(i int64) int

CountIntByte Calculate the number of bytes occupied after conversion to a string 1 = 1 ,10 = 2, 222 = 3 1000 = 4, 10000 = 5

func IsDirExists

func IsDirExists(path string) bool

IsDirExists check dir return true if exists

func StringToBytes

func StringToBytes(s string) []byte

StringToBytes convert string to bytes return-value read-only Please pay attention to the life cycle of the object when using this function

Types

type Frame

type Frame uintptr

Frame represents a program counter inside a Stack frame. For historical reasons if Frame is interpreted as an uintptr its value represents the program counter + 1.

func (Frame) Format

func (f Frame) Format(s fmt.State, verb rune)

Format formats the frame according to the fmt.Formatter interface.

%s    source file
%d    source line
%n    function name
%v    equivalent to %s:%d

Format accepts flags that alter the printing of some verbs, as follows:

%+s   function name and path of source file relative to the compile time
      GOPATH separated by \n\t (<funcName>\n\t<path>)
%+v   equivalent to %+s:%d

func (Frame) MarshalText

func (f Frame) MarshalText() ([]byte, error)

MarshalText formats a stacktrace Frame as a text string. The output is the same as that of fmt.Sprintf("%+v", f), but without newlines or tabs.

type Stack

type Stack []uintptr

Stack represents a Stack of program counters.

func Callers

func Callers() *Stack

Callers returns Stack

func (*Stack) Format

func (s *Stack) Format(st fmt.State, verb rune)

Format formats the Stack of Frames according to the fmt.Formatter interface.

func (*Stack) StackTrace

func (s *Stack) StackTrace() StackTrace

StackTrace returns formatted StackTrace of the stack.

type StackTrace

type StackTrace []Frame

StackTrace is Stack of Frames from innermost (newest) to outermost (oldest).

func (StackTrace) Format

func (st StackTrace) Format(s fmt.State, verb rune)

Format formats the Stack of Frames according to the fmt.Formatter interface.

%s	lists source files for each Frame in the Stack
%v	lists the source file and line number for each Frame in the Stack

Format accepts flags that alter the printing of some verbs, as follows:

%+v   Prints filename, function, and line number for each Frame in the Stack.
