crystal-lru

Yet another Crystal LRU Cache library that I use for my Crystal projects.

Installation

  1. Add the dependency to your shard.yml:

    dependencies:
  lru:
    github: fijxu/crystal-lru

  2. Run shards install

Usage

require "lru"

Log.setup(:trace)

max_size = 100
# By default, clean_interval is set to 1.seconds, but it can also be nil!
clean_interval = 1.seconds

cache = LRUCache(String).new(max_size, clean_interval)

# Set item to the cache
cache.set("key", "value", 5)
cache.set("key2", "value2")

pp cache.get("key") # => "value"
pp cache.get("key2") # => "value2"
pp cache.get("unknown") # => nil

cache.del("key2")

pp cache.get("key2") # => nil

Development
