Types ¶
type Frame ¶
type Frame uintptr
Frame represents a program counter inside a stack frame.
func (Frame) Format ¶
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
type Stack ¶
type Stack []uintptr
func NewStackSkip ¶
func (Stack) StackTrace ¶
func (st Stack) StackTrace() StackTrace
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.
func (StackTrace) FormatStackTrace ¶
func (st StackTrace) FormatStackTrace(s fmt.State, verb rune)
type StackTraceFormatter ¶
StackTraceFormatter is an alternative to StackTracer that only uses standard library types In practice the stack trace is usually only used for printing. With this definition a package can define a printing of a stack trace without importing this package.
type StackTracer ¶
type StackTracer interface {
StackTrace() StackTrace
}
StackTracer retrieves the StackTrace
