Instance Method Details

#caller_method_name(caller_index = 0) ⇒ String

See:

- Make this fast because its often doing logging & reporting. Inline this and use $1 because it’s empirically faster than /1

These two methods must always be equal:

caller_method_name(0) === my_method_name

Examples:

def foo
  puts caller_method_name(0)
  puts caller_method_name(1)
end
=> 
"foo"
"irb_binding"

Returns:

  • (String) —

    the method name of the caller at the index
