Constructor Details

#initialize(hash = nil, prefix = 'redis_struct', suffix = nil, database) ⇒ RedisStruct

An RedisStruct wraps the OpenStruct class, which uses method_missing to store values in a hash. Instead, RedisStruct stores these values in Redis, providing a pleasant way of interfacing with $redis.

#When $redis = Redis.new :host => ‘0.0.0.0’, :port => ‘6379’ example = RedisStruct.new($redis)

example.color = ‘blue’

example.color # => ‘blue’

The hash will load any data you want into the RedisStruct, without having to iterate over it. And the prefix is what’s used to store in $redis. Good luck!

Rewriting so RedisStruct#to_h doesn’t call RedisHash#dup
