They are of the following general form: template<{TemplateParameters>ClassTemplateName(ConstructorParameters) -> ClassTemplateSpecialization; Reference: en.cppreference.com/w/cpp/language/ 26 Jun 2017 But does it mean C++17 doesn't improve templates/template meta-programming? BTW: if you're really brave you can still use concepts! Also if you're adventurous you can create your custom class template deduction guides: see here for more information: recent post: Arne Mertz: Modern C++ Features 6 Feb 2017 This paper discusses possible extensions to template argument deduction for class templates as described in P0091R3. Please see that paper Indeed, we contend that supporting = delete for deduction guides not only increases consistency but has worthwhile use cases as well. Consider the following 15 Mar 2017 Template deduction guides are patterns associated with a template class that tell the compiler how to translate a set of parameter (and their types) into template arguments. The simplest example is that of std::vector and its constructor that takes an iterator pair. template void func(Iterator first, Iterator last) The syntax of a user-defined deduction guide is the syntax of a function declaration with a trailing return type, except that it uses the name of a class template as the function name: Abstract: Class Template Argument Deduction (CTAD) is a very useful C++ language feature that was added in C++17. In this talk, I will present how CATD lets you write cleaner and shorter code, show how it interacts with the C++ standard library, explain when and how user-defined deduction guides should be used, cover 11 Jan 2017 pair a{0, 42.42}; std::tuple t{"hi", 15, std::vector{}};. This feature is supported through a new concept known as deduction guides, which tell the compiler how to deduce template arguments for the template class from the constructor arguments. These can be implicitly synthesized, or explicitly specified. 29 Nov 2016 C++17's automatic class template deduction feature brings with it a new sub-feature called “deduction guides" which are used to help the compiler with class template type deduction. Jason gives examples of what they are and how they are used in this episode. Do you often use make functions to construct a templated object (like std::make_pair )? With C++17 you can forget about (most of) them and just use regular a Also if you're adventurous you can create your custom class template deduction guides: see here for more information: recent post: Arne Mertz: Modern C++ User defined deduction guides have to be defined in the same scope as the class template the$
