Topic: Profiling calls to a specific function inside another call

Let's say I have a low level function f which I call a LOT of times. I'm testing another high level function g which calls f MANY times. I normally profile g using @profview in VSCode. What if I'd like to:

call g
run f inside the call to g, profile it, show the result ONLY FOR f in VSCode profiler view and stop (a readline() is ok) so i can take notes
keep running g and stop (and do the same thing) the next time it calls f

Any way of doing this "interactive" profiling ?

I'm not familiar with vscode, but my understanding is that it has a built-in debugger. What's preventing you from doing profiling from inside the debugger (so long as you run the pieces you're interested in profiling in compiled rather than interpreted mode)?
