struct

问题 I'm looking for a way to use a function as an argument to another function in GLSL. In regular C, it can be simulated by passing a function pointer as a function argument. It also seems that other languages (like HLSL) now provide ways to deal with high-level constructs like higher-order functions, or can simulate them with clever use of HLSL structures. unfortunately I'm stuck with GLSL for now, and I can't find any way to simulate higher-order functions. Is it really impossible in current

问题 So I have and html template when using this I get the object: <div>Foobar {{ index .Doc.Users 0}}</div> Output: <div>Foobar {MyName my@email.com}</div> I just want to use the Name field I have tried many iterations without success: {{ index .Doc.Users.Name 0}} {{ index .Doc.Users 0 .Name}} {{ .Name index .Quote.Clients 0}} ... What is the correct syntax for just getting .Name field ( .Doc.Users[0].Name ) of the first element in my array? 回答1: Simply group the expression and apply the .Name

问题 How can I filter fields with the mongo-go-driver. Tried it with findopt.Projection but no success. type fields struct { _id int16 } s := bson.NewDocument() filter := bson.NewDocument(bson.EC.ObjectID("_id", starterId)) var opts []findopt.One opts = append(opts, findopt.Projection(fields{ _id: 0, })) staCon.collection.FindOne(nil, filter, opts...).Decode(s) In the end, I want to suppress the field "_id". But the documents didn't change. 回答1: The reason why it doesn't work for you is because

问题 Does anyone know what this error means and why it is occurring when I am trying to define an array inside a struct? struct test{ int idk[] = { 1,2,3 }; }; Why is the array idk incomplete type or something? Thanks in advance. Ps. I need this so I can access these arrays from the test struct. 回答1: When declaring a variable in a local scope (like in a function body, for example), you can do this and the compiler will not complain, it will deduce that you mean an array of int of 3 elements. void

问题 I need to create a stl::set of structures. Therefore, I wrote the following: stl::set <Point> mySet; // Point - name of the structure. Then I tried to add a structure instance to mySet as follows: Point myPoint; mySet.insert(myPoint); However, I get several compilation errors (error C2784, error C2676): 1>C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\xfunctional(125): error C2784: bool std::operator <(const std::vector<_Ty,_Ax> &,const std::vector<_Ty,_Ax> &): failed to bring

问题 New wannabe programmer here. I'm currently working on my homework and I encountered with some problems. The task is the following: FanControl function shall turn on the fan if the temperature is over the limit and it shall turn off the fan when the temperature is below the limit. 1.1. Hysteresis shall be applied on the switching limits symmetrically. 1.2. The hysteresis and the default limit shall be configurable on compile time. 1.2.1.The default limit shall be 25°C and the default
