Overview

Abstract base class for storage backends. Implement this protocol to create custom storage (Redis, PostgreSQL, etc.)

Example:

class RedisStorage < Classifier::Storage::Base
def initialize(redis:, key:)
  @redis, @key = redis, key
end

def write(data) = @redis.set(@key, data)
def read = @redis.get(@key)
def delete = @redis.del(@key)
def exists? = @redis.exists?(@key)
end
