What's this?

raw_data() public

Returns an Array of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME.

For example:

[
  {
     :GC_TIME=>1.3000000000000858e-05,
     :GC_INVOKE_TIME=>0.010634999999999999,
     :HEAP_USE_SIZE=>289640,
     :HEAP_TOTAL_SIZE=>588960,
     :HEAP_TOTAL_OBJECTS=>14724,
     :GC_IS_MARKED=>false
  },
  # ...
]

The keys mean:

`:GC_TIME`	Time elapsed in seconds for this GC run
`:GC_INVOKE_TIME`	Time elapsed in seconds from startup to when the GC was invoked
`:HEAP_USE_SIZE`	Total bytes of heap used
`:HEAP_TOTAL_SIZE`	Total size of heap in bytes
`:HEAP_TOTAL_OBJECTS`	Total number of objects
`:GC_IS_MARKED`	Returns `true` if the GC is in mark phase

If ruby was built with GC_PROFILE_MORE_DETAIL, you will also have access to the following hash keys:

`:GC_MARK_TIME`
`:GC_SWEEP_TIME`
`:ALLOCATE_INCREASE`
`:ALLOCATE_LIMIT`
`:HEAP_USE_PAGES`
`:HEAP_LIVE_OBJECTS`
`:HEAP_FREE_OBJECTS`
`:HAVE_FINALIZE`
