Cache::LRU(3)

🦋 Cache::LRU(3) — the pure-perl LRU cache that's lowkey iconic 🦋

Okay bestie, this is the Cache::LRU(3) page from User Contributed Perl Documentation, and it's giving “simple, fast, in-memory LRU cache, written in pure perl.” No cap. Let's get into it. 💅

NAME 🎀

Cache::LRU - a simple, fast implementation of LRU cache in pure perl.

SYNOPSIS ✨

use Cache::LRU;

my $cache = Cache::LRU->new(
    size => $max_num_of_entries,
);

$cache->set($key => $value);

$value = $cache->get($key);

$removed_value = $cache->remove($key);

DESCRIPTION 🌸

Cache::LRU is a simple, fast implementation of an in-memory LRU cache in pure perl. That's the whole vibe: it caches stuff in memory, it does LRU things, and it's pure perl. Periodt. 💖

FUNCTIONS 🧚

Cache::LRU->new(size => $max_num_of_entries) 👑

Creates a new cache object. Takes a hash as the only argument. The only parameter currently recognized is the size parameter, which specifies the maximum number of entries to be stored within the cache object. Slay. 🫶

$cache->get($key) 🔍

Returns the cached object if it exists, or undef otherwise. That's it. That's the function. 💅

$cache->set($key => $value) 📥

Stores the given key-value pair. Very demure, very mindful. 🎀

$cache->remove($key) 🗑️

Removes data associated to the given key and returns the old value, if any. So you get the ex-content back, iykyk. 💀

$cache->clear($key) 🧹

Removes all entries from the cache. Yes, the signature says $cache->clear($key); the job is still “nuke every entry.” No notes. 😭

AUTHOR 👑

Kazuho Oku. Iconic behavior. 🌟
