package redismemo // import "gopkg.makigas.es/redismemo"

Package redismemo provides a basic memoization system around Redis.

It works by wrapping a go-redis/v9 client and providing a simple function that
can be used to fetch a value from Redis given its key, as well as the compute
function to be issued if the value is not found in the Redis instance. If the
value has to be computed, it is also set in the Redis instance using the given
TTL, which comes handy for caches.

TYPES

type Compute func() string
    Compute is a lazy function that when evaluated returns a string value.
    Computes are used as a fallback if the cache does not hold the given key.

type Memo func(ctx context.Context, key string, value Compute, exp time.Duration) (string, error)
    Memo is a function that memoizes values in a cache. Memo returns the string
    identified by the given cache key. If the cache does not hold the key,
    it computes the value and stores it with the given expiration TTL.

func RedisMemo(rdb *redis.Client) Memo
    RedisMemo wraps a Redis client to provide a memoization function.
