Types

type IBoolCacher

type IBoolCacher interface {
	ICloser
	GetBool(ctx context.Context, key string) (bool, error)
	SetBool(ctx context.Context, key string, value bool, expiration time.Duration) error
}

IBoolCacher 布尔缓存

type ICacher

type ICacher interface {
	ISimpleCacher
	IIntCacher
	IFloatCacher
	IObjectCacher
	IBoolCacher
	IKeyPrefixCacher
	// SetNX 设置缓存，如果key存在则返回false
	SetNX(ctx context.Context, key string, value string, expiration time.Duration) (bool, error)
}

ICacher 缓存

func NewFreeCache

func NewFreeCache(cli *freecache.Cache) ICacher

NewFreeCache 创建一个默认的缓存

func NewNutsDbCacher

func NewNutsDbCacher(client *nutsdb.DB, bucket string) ICacher

NewNutsDbCacher creates a new nutsdb cache client.

func NewRedisCacher

func NewRedisCacher(cli *redis.Client) ICacher

NewRedisCacher creates a new redis cacher

type ICloser

type ICloser interface {
	Close() error
}

ICloser 关闭缓存

type IFloatCacher

type IFloatCacher interface {
	ICloser
	GetFloat64(ctx context.Context, key string) (float64, error)
	SetFloat64(ctx context.Context, key string, value float64, expiration time.Duration) error
}

IFloatCacher 浮点数缓存

type IIntCacher

type IIntCacher interface {
	ICloser
	// Inc 增加缓存值
	Inc(ctx context.Context, key string, expiration time.Duration) (int64, error)
	// Dec 减少缓存值
	Dec(ctx context.Context, key string, expiration time.Duration) (int64, error)
	// IncMax 增加缓存值，如果超过max则返回max
	IncMax(ctx context.Context, key string, max int64, expiration time.Duration) (bool, error)
	// DecMin 减少缓存值，如果小于min则返回min
	DecMin(ctx context.Context, key string, min int64, expiration time.Duration) (bool, error)
	// GetInt64 获取缓存
	GetInt64(ctx context.Context, key string) (int64, error)
	// SetInt64 设置缓存
	SetInt64(ctx context.Context, key string, value int64, expiration time.Duration) error
}

IIntCacher 整数缓存

type IKeyPrefixCacher

type IKeyPrefixCacher interface {
