Looks like a cache but doesn’t perform any caching. This helps us avoid checking for whether a cache is configured or not, as per the Null Object pattern: en.wikipedia.org/wiki/Null_Object_pattern.

Instance Method Details

#fetch(cache_key) ⇒ Object

Returns the value of the yielded block. Assumes that a block is passed; ActiveSupport::Cache::Store#fetch allows for no block but we don’t use this internally. Ignores cache_key because no caching is performed.
