type Cache

type Cache[V any] struct {
	TTL    time.Duration
	Client *redjet.Client
	// Prefix is the prefix used for all keys in the cache.
	Prefix string
}

Cache is a simple cache implementation using Redis as a backend.

func (*Cache[V]) Do

func (c *Cache[V]) Do(
	ctx context.Context,
	key string,
	fn func() (V, error),
) (V, error)

Do executes fn and caches the result for key. If the value is already cached, it is returned immediately.

Do uses JSON to marshal and unmarshal values. It may not perform well for large values.
