    [cpu-profiler] Add method to estimate mem size of ProfilerCodeObserver · 731fd3f5
    Corentin Pescheloche authored
    This patchset introduces instrumentation of the memory usage of the
    datatructures maintained by the CPU profiler.
    It captures:
    * The total size of the strings held in StringsStorage for CodeEntries
    * Estimated size held by CodeMap's entries.
    
    The target is to surface that metric through telemetry to get better
    visibility into the memory profile of CpuProfiler.
    
    For now, STL containers overhead is ignored as it is implementation
    specific.
