Types

type Cache

type Cache interface {
	// GetLocal returns the object in local cache, if it exists.
	// Returns true if found, false if not found
	Get(id string, out interface{}) bool

	// Set both remote and local caches
	Set(element Cacheable) error

	// SetRaw lets you choose the id instead of relying on the Cacheable interface
	SetRaw(id string, element interface{}) error

	// Drop both remote and local cache entry
	Drop(ids ...string) error

	// Flush removes all entries in remote and local cache
	Flush() error
}

Cache unifies cache usage across the project.

func NewKV

func NewKV() Cache

NewKV is a local Key: Value storage using a stock golang map[string]interface{}. Very useful for tests but could be used for any local cache.

func NewThreadSafeCache

func NewThreadSafeCache(c Cache) Cache

NewThreadSafeCache creates the wrapped cache

type Cacheable

type Cacheable interface {
	CacheID() string
}

Cacheable makes your struct cache-able

type KVCache

type KVCache struct {
	// contains filtered or unexported fields
}

KVCache is a simple map[string]interface{} so you get a very simple local key:value storage.
