Types

type CacheStore

type CacheStore interface {
	Get(key string, value interface{}) error
	Set(key string, value interface{}, expire time.Duration) error
	Add(key string, value interface{}, expire time.Duration) error
	Replace(key string, data interface{}, expire time.Duration) error
	Delete(key string) error
	Increment(key string, data uint64) (uint64, error)
	Decrement(key string, data uint64) (uint64, error)
	Flush() error
}

CacheStore is the basic interface for cache implementations

type InMemoryStore struct {
	cache.Cache
}

func NewInMemoryStore

func NewInMemoryStore(defaultExpiration time.Duration) *InMemoryStore

func (*InMemoryStore) Add

func (c *InMemoryStore) Delete(key string) error

func (*InMemoryStore) Flush

func (c *InMemoryStore) Flush() error

func (*InMemoryStore) Get

	*memcache.Client
	// contains filtered or unexported fields
}

func (*MemcachedStore) Delete

func (c *MemcachedStore) Delete(key string) error

func (*MemcachedStore) Flush

func (c *MemcachedStore) Flush() error

func (*MemcachedStore) Get

func (c *MemcachedStore) Get(key string, value interface{}) error

func (*MemcachedStore) Increment

func (c *MemcachedStore) Increment(key string, delta uint64) (uint64, error)

func (*MemcachedStore) Replace

func (c *MemcachedStore) Replace(key string, value interface{}, expires time.Duration) error

func (*MemcachedStore) Set

func (c *MemcachedStore) Set(key string, value interface{}, expires time.Duration) error

type RedisStore

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

Wraps the Redis client to meet the Cache interface.

func NewRedisCache

func NewRedisCache(host string, password string, defaultExpiration time.Duration) *RedisStore

until redigo supports sharding/clustering, only one host will be in hostList

func (*RedisStore) Flush

func (c *RedisStore) Flush() error

func (*RedisStore) Get

func (c *RedisStore) Get(key string, ptrValue interface{}) error

func (*RedisStore) Increment

func (c *RedisStore) Increment(key string, delta uint64) (uint64, error)

func (*RedisStore) Replace

func (c *RedisStore) Replace(key string, value interface{}, expires time.Duration) error

func (*RedisStore) Set
