module function ObjectSpace.#count_objects_size

count_objects_size(result_hash = nil) -> Hash [added by objspace]

Counts objects size (in bytes) for each type.

Note that this information is incomplete. You need to deal with this information as only a *HINT*. Especaially, total size of T_DATA may not right size.

It returns a hash as:

{:TOTAL=>1461154, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249, ...}

If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.

The contents of the returned hash is implementation defined. It may be changed in future.

This method is not expected to work except C Ruby.
