More elaborated example of registering a global template function?

Hi,

I am trying to register a global template function and I feel a bit lost following the doc found here: https://www.angelcode.com/angelscript/sdk/docs/manual/doc_adv_template_func.html

Here's what I have attempted, but it seems that AS complains anout the signature already:

void EcsField(asIScriptGeneric* Generic)
{
	auto Engine = FAngelscriptManager::Get().GetScriptEngine();
	auto CompTypeAS = Generic->GetReturnTypeId();
	FFlecsIterator* Iterator = reinterpret_cast<FFlecsIterator*>(Generic->GetArgAddress(0));
	int FieldId = Generic->GetArgDWord(1);
	auto TypeInfo = Engine->GetTypeInfoById(CompTypeAS);
	if (TypeInfo == nullptr) FAngelscriptManager::Throw("Cannot find type info for component");
	void* Data = ecs_field_w_size(&Iterator->Iterator, TypeInfo->GetSize(), FieldId);
	new(Generic->GetAddressOfReturnLocation()) void*(Data);
}

AS_FORCE_LINK const FAngelscriptBinds::FBind Bind_FFlecsIterator(FAngelscriptBinds::EOrder::Late, []
{
	auto Engine = FAngelscriptManager::Get().GetScriptEngine();
	auto r = Engine->RegisterGlobalFunction("T@ EcsField<T>(FFlecsIterator@ It, int FieldIndex)", 
		asFUNCTION(EcsField), asCALL_GENERIC);
	check(r >= 0);
});
