instance method

Thread::Backtrace::Location#label

() -> ::String?

label

static VALUE
location_label_m(VALUE self)
{
    return location_label(location_ptr(self));
}

Returns the label of this frame.

Usually consists of method, class, module, etc names with decoration.

Consider the following example:

Example

def foo
  puts caller_locations(0).first.label

  1.times do
    puts caller_locations(0).first.label

    1.times do
      puts caller_locations(0).first.label
    end
  end
end

The result of calling foo is this:

foo
block in foo
block (2 levels) in foo
