#alloc_percent_for(method_info) ⇒ Object

Returns allocation percentage for a method (0.0-100.0) method_info can be a Hash with :name and/or :file keys, or a String method name

  return nil unless frame

  frame[:alloc_percent]
end

#cpu_percent_for(_method_info) ⇒ Object

Returns CPU percentage for a method (0.0-100.0) Always returns nil for MemoryProfiler since it tracks allocations, not CPU
