I have a goroutine with a switch which want to append an interface to a struct but when a run it I don't receive an error but it not append any response How do you write that in Go to make it concurrency-safe?
This is my code:
var wg sync.WaitGroup
for _, v := range inputParameters.Entities {
go func(v domain.Entity) {
wg.Add(1)
defer wg.Done()
var f func(
v domain.Entity,
result *domain.Resoponse,
)(interface{}, Error) // Signature of all Get methods
switch v.Name {
case "process1":
f = 1Processor{}.Get
case "process2":
f = 2Processor{}.Get
case "process3":
f = 3Processor{}.Get
default:
return
}
res, err := f(v, result)
if err != nil {
mapError.Error = append(mapError.Error, err)
} else {
result.Mu.Lock()
defer result.Mu.Unlock()
result.Entities = append(result.Entities, res)
}
}(v)
}
wg.Wait()
return result, mapError
For reference, here is the Response
type:
type Resoponse struct {
Mu sync.Mutex
Entities []interface{}
}
