Cache::Ref::Null(3pm)

✨ NAME ✨

Cache::Ref::Null — bestie, this thing caches absolutely nothing. Zero. Nada. A void. 💅

It's part of the Cache::Ref family, and yeah, the manual page header calls it Cache::Ref::Null(3pm) if you're keeping score. 🎀

---

🌸 SYNOPSIS 🌸

# useful for comparing the effect of a cache compared to no
# caching without code changes:

my $c = Cache::Profile::Compare->new(
    caches => [
        Cache::Ref::Foo->new( ... ),
        Cache::Ref->Null->new,
    ],
);

okay so the whole point of this snippet is the vibe of fairness 🧚 — you drop the no-op cache in next to a real one so you can compare, without touching your actual code. iconic behaviour, honestly.

🦋 DESCRIPTION 🦋

This cache implementation will cache nothing. 🫶

That's it. That's the whole personality. It's the main character of doing nothing.

It's primarily intended for testing or for comparing runtime without a cache against runtime with a cache — like a control group but for your benchmark, no cap. 🔥

It's like Cache::Null but supports the additional methods in Cache::Ref. so it slots into your Cache::Ref-shaped hole perfectly, lowkey the most useful useless module ever. 💀

ngl if you're expecting this to speed something up you're gonna have a bad time — it literally cannot remember anything, that's the entire bit.
