How to use runtime type reflection to convert types?

Question content

I'm trying to build a function using generics that converts an interface slice into a slice of type t.

I came up with the following:

func convertInterfaceArray[T any](input []any, res []T) {
    for _, item := range input {
        res = append(res, item.(reflect.TypeOf(res[0])))
    }
}
Copy after login

However, this will not compile. But you get the point. t can be of any type, I have an input slice of type []any that needs to be converted to []t


Correct Answer


Assertion Typet value. No reflection required.

for _, item := range input {
    res = append(res, item.(T))
}
Copy after login
