是否可以接收实现特定接口的所有结构？

Question

I checked the reflect package documentation, but didn't find anything. What i'm trying to do is find all structs, that implement interface x. Then iterate over all the structs to execute an action y.

Answer 1

This cannot be done at runtime, but only statically by inspecting the program packages (and all of the imports recursively). Or by statically inspecting the generated .{o,a} files.

However, one may manually build a list of types (not limited to only structs, why?) satisfying an interface:

if _, ok := concreteInstance.(concreteInterface); ok {
        // concreteInstance satisfies concreteInterface
}
