Functions ¶

func ExternalCaller ¶

func ExternalCaller() *runtime.Frame

ExternalCaller returns the first frame outside the callers package.

func Frames ¶

func Frames(skip, max int) []runtime.Frame

Frames returns at most max callstack Frames, starting with its caller and skipping skip Frames.

func Main ¶

func Main() *runtime.Frame

Main returns the main() function Frame.

func Match ¶

func Match(skip int, predicate func(runtime.Frame) bool) *runtime.Frame

Match returns the first stack frame for which the predicate function returns true. Returns nil if no match is found. Starts matching after skip frames, starting with its caller.
