Can You Get a `reflect.Type` from a String Name in Go?

Getting reflect.Type from Type Name in Go

Consider the following task:

type t1 struct { i int; s string }

How can you obtain the reflect.Type of t1 without instantiating it?

• Can you get the reflect.Type without instantiation?

Yes, it's possible:

var v1 reflect.Type = reflect.TypeOf((*t1)(nil)).Elem()

You can use reflect.TypeOf to get the reflect.Type of a pointer to a nil struct of type t1, and then use Elem to get the type of the underlying struct.

• Can you get the reflect.Type from the string name "t1"?

Unfortunately, no. Go does not maintain a map of types in the current binary, making it impractical to retrieve a type from a string. While it is possible to create a custom type registry package, it would be incomplete and potentially ambiguous due to anonymous types and name collisions.
