我想知道的是Ruby用于特定Hash对象的字节数。如何做到这一点？

All I want to know is how many bytes Ruby is using for a particular Hash object. How do I do that?

推荐答案

在2010年GoGaRuCo上的Ruby 1.9上，我了解了一些添加到ObjectSpace的东西， 1.9这似乎是诀窍。

In tenderlove's talk on Ruby 1.9 at GoGaRuCo 2010, I learned about some stuff added to ObjectSpace in 1.9 that would seem to do the trick.

require "objspace"
obj = {some:"STUFF"}
ObjectSpace.memsize_of(obj) # => you can imagine

找到一些 docs on objspace ，但很多都是日文。

Found some docs on objspace but a lot of it is Japanese. There's some English in there if you keep looking.

仍然不确定如何使用Ruby获取1.8.7中对象的内存大小。

Still not sure how I can get the memory size of an object in 1.8.7 by using Ruby.
