Functions

func Err

func Err(format string, args ...any) error

Err formats according to a format specifier and returns the string as a value that satisfies error. Err also records the stack trace at the point it was called.

func Error

func Error(err error) error

Error wraps an error into a StructError, recording the stack trace and a default message.

func Errorf

func Errorf(err error, format string, args ...any) error

Errorf wraps an error into a StructError, appending a formatted message. If the error is already a StructError, it appends the message to the existing one.

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 (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 StructError

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

func (*StructError) Error

func (w *StructError) Error() string

func (*StructError) Format

func (w *StructError) Format(s fmt.State, verb rune)

func (*StructError) Message

func (w *StructError) Message() string

func (*StructError) Stack

func (w *StructError) Stack() StackTrace

func (StructError) StackTrace

func (s StructError) StackTrace() StackTrace

func (*StructError) Unwrap

func (w *StructError) Unwrap() error

Unwrap provides compatibility for Go 1.13 error chains.
