Cache:...Expiry(3pm)

🌸 NAME 🌸

Cache::Simple::TimedExpiry — it's giving simple, time-expiring cache ✨ bestie it literally does what it says on the tin, an in-memory cache where the entries just… expire. iconic behavior honestly 💅

---

✨ EXAMPLE ✨

okay so here's the whole vibe in one script, no cap:

package main;

use strict;
use warnings;
$,=' '; $|++;

use Cache::Simple::TimedExpiry;
my $h =  Cache::Simple::TimedExpiry->new;

$h->set( DieQuick => "No duration!", 0);
print $h->elements;
do { $h->set($_,"Value of $_", 1); sleep 2;}
   for qw(Have a nice day you little monkey);

print $h->elements; $h->dump; sleep 4; print $h->elements; $h->dump;

print time;

like, watch it set stuff, sleep, and watch the entries ✨vanish✨ in real time 🦋

🎀 new

Set up a brand new cache object 🫶 that's it, that's the whole job, and she ate.

⏳ expire_after SECONDS

Set the cache's expiry policy so entries expire after SECONDS seconds. 🕰️ And here's the tea bestie — setting this changes the expiry policy for pre-existing cache entries AND for new ones, so don't think you're sneaking the old ones past her 💀

🔑 has_key KEY

Returns true if the cache has an entry with the key KEY 👑 simple as. Returns false otherwise, obviously, iykyk.

🍓 fetch KEY

Returns the cache entry with key KEY. If there's no such entry it returns undef 😭 (yes, the sad little nothing-value, we've all been there).

💡 bonus: you can also call it as get — two names, one icon 🫶

💾 store KEY VALUE

Stores VALUE in the cache with accessor KEY. Expire it from the cache at or after EXPIRYTIME. 🎀

💡 bonus again: you can also call it as set — she's flexible like that ✨
