How to convert interface{} to map

Question

I am trying to create a function that could accept following

*struct
[]*struct
map[string]*struct

Here struct could be any struct not just a sp

Another way to convert an interface{} into a map with the package reflect is with MapRange.

I quote:

MapRange returns a range iterator for a map. It panics if v's Kind is not Map.

Call Next to advance the iterator, and Key/Value to access each entry. Next returns false when the iterator is exhausted. MapRange follows the same iteration semantics as a range statement.

Example:

iter := reflect.ValueOf(m).MapRange()
for iter.Next() {
    key := iter.Key().Interface()
    value := iter.Value().Interface()
    ...
}
