How to handle array variable in registercallback function

[karthi8185]

Hi,
I am using opentelemetry to export some customize data to otelcollector. Here my question is any possibility to pass the array arguments into RegisterCallback()

In the below code, instead of passing name1[0], name1[1], name1[2]... any possibility of send name1. Also, is there any api/method to resolve the type converstion. Since name1 data type is metric.Int64ObservableCounter but register to call back argument is metric.Observable.

var name1 []metric.Int64ObservableCounter
......
_, err = meter.RegisterCallback(
func(ctx context.Context, o metric.Observer) error {
o.ObserveInt64(name1[0], int64(getMetricValue(fullName1)))
o.ObserveInt64(name1[1], int64(getMetricValue(fullName2)))
o.ObserveInt64(name1[2], int64(getMetricValue(fullName3)))
o.ObserveInt64(name1[3], int64(getMetricValue(fullName4)))
return nil
},
name1[0],
name1[1],
name1[2],
name1[3],
)

kindly guide me.
