Functions ¶

func Uint64 ¶

func Uint64(v int64, err error) (uint64, error)

Types ¶

type Generic ¶

type Generic interface {
	Exists(ctx context.Context, key string) (bool, error)
	TTL(ctx context.Context, key string) (time.Duration, error)
	Del(ctx context.Context, key string) (uint32, error)
}

type JsonMarshaller ¶

type JsonMarshaller struct{}

func (*JsonMarshaller) Marshal ¶

func (jm *JsonMarshaller) Marshal(v interface{}) ([]byte, error)

func (*JsonMarshaller) Unmarshal ¶

func (jm *JsonMarshaller) Unmarshal(data []byte, v interface{}) error

type Mode ¶

type Mode uint8

const (
	Single Mode = iota
	Cluster
)

type ObjMarshaller ¶

type ObjMarshaller interface {
	Marshal(interface{}) ([]byte, error)
	Unmarshal([]byte, interface{}) error
}

type Object ¶

type Object interface {
	GetObject(ctx context.Context, key string, obj interface{}) error
	SetObject(ctx context.Context, key string, obj interface{}) error
	SetObjectEx(ctx context.Context, key string, obj interface{}, expiration time.Duration) error
}

type ProtoMarshaller ¶

type ProtoMarshaller struct{}

func (*ProtoMarshaller) Marshal ¶

func (pm *ProtoMarshaller) Marshal(v interface{}) ([]byte, error)

func (*ProtoMarshaller) Unmarshal ¶

func (pm *ProtoMarshaller) Unmarshal(data []byte, v interface{}) error

type RedisClient ¶

type RedisClient interface {
	io.Closer
	Generic
	String
	Object
}

RedisClient introduce all the gredis method we need for gredis bot and also with context support

func NewRedisClient ¶

func NewRedisClient(option *RedisClientOption) (RedisClient, error)

NewRedisClient create a redisClient object from config it will create bot connect to single, ring or cluster based on the configuration currently we only support redisClient, may add more in the future (for example , v9Client?), so we return an interface

func NewRedisClientByConfig ¶

func NewRedisClientByConfig(cfg env.ModuleConfig, redisDBKey string) (RedisClient, error)

type RedisClientOption ¶

type RedisClientOption struct {
	Mode                Mode
	Addr                string
	Password            string
	Db                  int
	PoolSize            int
	Addrs               map[string]string
	ClusterAddrs        []string
	ClusterMaxRedirects int
	ClusterReadOnly     bool
	DialTimeout         time.Duration
	ReadTimeout         time.Duration
	WriteTimeout        time.Duration
	Marshaller          ObjMarshaller
}

RedisClientOption gredis bot option

type SelfMarshaller ¶

type SelfMarshaller interface {
	Marshal() ([]byte, error)
	Unmarshal([]byte) error
}

type SortedSet ¶

type SortedSet interface {
	ZAdd(ctx context.Context, key string, value interface{}, expiration time.Duration) (bool, error)
}

type String ¶

type String interface {
	SetNX(ctx context.Context, key string, value interface{}, expiration time.Duration) (bool, error)
	Set(ctx context.Context, key string, value interface{}) error
	SetEx(ctx context.Context, key string, value interface{}, expiration time.Duration) error
	Get(ctx context.Context, key string) (string, error)
	Incr(ctx context.Context, key string) (int64, error)
	IncrBy(ctx context.Context, key string, value int64) (int64, error)
}
