Noob question, why my class does not compile when I add a structure?

Development Programming & Scripting C++

Trying to learn c++ but I am stuck trying to add a structure in a blueprint library.
Here is the header file:


#pragma once
#include "Kismet/BlueprintFunctionLibrary.h"
#include "MyBlueprintFunctionLibrary.generated.h"
USTRUCT(BlueprintType)
struct FMultipleVarOut
{
	GENERATED_USTRUCT_BODY()

		UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "My Struct")
		bool bBoolOut;
	//Constructor
	FMultipleVarOut()
	{
		bBoolOut = true;
	}
	//Set
	void SetBoolOut(const bool NewValue)
	{
		bBoolOut = NewValue;
	}
	bool GetBoolOutProperty()
	{
		return bBoolOut;
	}
};
UCLASS()
class C_TUTORIAL_API UMyBlueprintFunctionLibrary :  UBlueprintFunctionLibrary
{
	GENERATED_BODY()

		UFUNCTION(BlueprintCallable, Category = MyCategory)
		static bool test(bool yo);
	
};

The compiler errors:

Did you try it in it’s own .h and .cpp files and not share with another class?

Just tried the same struct inside an actor and it works. It just does not work inside the blueprint function library, strange
