Types

type Frame

type Frame uintptr

Frame represents a program counter inside a stack frame. For historical reasons if Frame is interpreted as a 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 StackTrace

type StackTrace []Frame

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

func GetStackTrace

func GetStackTrace(skip int) StackTrace

GetStackTrace gets the stack trace.

func PanicStackTrace

func PanicStackTrace() StackTrace

PanicStackTrace gets the panic stack trace.

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.

type Status

type Status struct {
	// contains filtered or unexported fields
}

func New

func New(code int32, msg string, cause ...interface{}) *Status

New 传入错误码，错误消息，错误原因，创建一个状态结构对象

func (*Status) TagStack

func (that *Status) TagStack(skip ...int) *Status

TagStack 栈堆结构

func (*Status) UnknownError

func (that *Status) UnknownError() bool

UnknownError 是否为未知错误

func (*Status) UnmarshalJSON
