* [benchmark] Introduce accessors for currently public data members `threads` and `thread_index` Also deprecate the direct access to these fields. Motivations: Our internal library provides accessors for those fields because the styleguide disalows accessing classes' data members directly (even if they're const). There has been a discussion to simply move internal library to make its fields public similarly to the OSS version here, however, the concern is that these kinds of direct access would prevent many types of future design changes (eg how/whether the values would be stored in the data member) I think the concensus in the end is that we'd change the external library for this case. AFAIK, there are three important third_party users that we'd need to migrate: tcmalloc, abseil and tensorflow. Please let me know if I'm missing anyone else. * [benchmark] Introduce accessors for currently public data members `threads` and `thread_index` Also deprecate the direct access to these fields.
