In the following snippet I have reconstructed a small failing example of what I'm working on right now. The class entity should be able to gobble up d ...
Suppose I need to write a function which might take either a constant reference to an lvalue or a temporary value, is there any advantage in terms of ...
I have a class object that takes universal parameters which are constrained to a certain concept. Now I want to forward this parameter (which type is ...
When I try to define a constructor taking a universal reference with a defaulted value as a parameter like this: struct S { int x; // I know that ...
I'm trying to implement a push function for a blocking queue which accepts a universal reference as it's template parameter, but requires that the tem ...
Hello I would like to ask, is it "good" (ok) or bad practise to store ref in parents state? What I need: Lets assume we have parent component WRA ...
Lets consider ordinary perfect forwarding: So far everything is fine. But if we now introduce a function pointer I get the problem that I seem not ...
I am trying to use an API which sets a value of a variable based on an HTTP call. The function in which I can set the variable which will be set upon ...
In the book "Effective Modern C++" by Scott Meyers the advice is given (item 26/27) to "Avoid overloading on universal references". His rationale for ...
How can I deal with universal reference, when I want either to copy semantics with a function parameter const T& or move semantics with function p ...
Following errors are seen on compilation o1 is obtained by instantiating template class Test with "A". So the call o1.func1(a) should know that v ...
The whole premise about forwarding references (aka universal references) is, that this function: can result in the template parameter either being ...
Consider the following code: I'm trying to understand what are the design benefits/drawbacks of each of the 2 constructor implementations. Also, ar ...
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0644r1.html says There are two ways that you can forward a variable: you can use std::for ...
i am a bit confused on the usage of std::forward with a specific use-case. Let's assume the following: Which of the //1 or //2 return statements is ...
Here is an algorithm std::shuffle from https://en.cppreference.com/w/cpp/algorithm/random_shuffle: Why the algorithm takes a forwarding ref ...
I have functions that take values and pass them to other functions. Nobody down the chain will ever care if it's an rvalue reference and they just wan ...
I encounter the pass by value and move idiom quite often: But it seems to me that passing by either const reference or rvalue reference can save a ...
Take a look at these two overloaded function templates: I call foo in the following way: And overload #1 is unambiguously chosen: https://gcc.go ...
