Types

type Script

type Script struct {
	*redis.Script
}

Script is script optimization class.

func New

func New(src string) *Script

New creates a new redis script optimizer object.

func (*Script) RunEx

func (s *Script) RunEx(ctx context.Context, c redis.Scripter, keys []string, args ...interface{}) *redis.Cmd

RunEx executes the lua script. If the script does not exist on the server, it will be executed and uploaded through Eval, and if it exists, it will be executed through EvalSha However: in pipeline mode, if redis.Script.Run executes EvalSha and reports that the script does not exist, it will not be able to call Eval to retry, so optimization is prohibited in pipeline mode.
