Defined in:: lib/tiny_struct/memory_cache.rb

Overview

Maintains an in-memory cache of the defined TinyStruct classes, such that classes with the same attribute list do not end up getting created twice.

This cache makes performance quite a bit better since looping through ObjectSpace takes a while, but takes a hit on memory because everything is now stored. Also prevents the classes from being freed if they were created anonymously and could have otherwise have been freed.
