This is a circuitbreaker module which is easy to use when you build your microservice.
// func NewCirucuitBreaker(timeWin time.Duration, failCnt int, failPercent int) *Circuits
// create an instance of circuitbreaker
cbs := NewCirucuitBreaker(time.Second, 150, 20)
// register a command to a circuitbreaker
suc := cbs.RegisterCommandAsDefault(testcmd)
// report a result (true or false) to a circuit with the command-name
cbs.Report(testcmd, false)
cbs.Report(testcmd, true)
// to check if current request could be allowed
execAllow := cbs.AllowExec(testcmd)$ go test
