WebFeb 13, 2024 · I use static polymorphism in the function template execution (lines 29 - 32). I invoke on each argument base the method base.interface. The method Base::interface in lines 7 - 9 is the critical point of the CRTP idiom. The methods dispatch to the implementation of the derived class: static_cast(this)->implementation().That … WebAug 4, 2024 · This doesn't appear to be related to the Curiously Recurring Template Pattern, though. CRTP has to do with inheriting from a base class parameterized with Self. Rust doesn't have classes or inheritance, so the idiom really doesn't translate. My understanding is that it's mostly used for two things: 1) to achieve compile time …
Web这也正是crtp这种设计的目的。 crtp的优点是什么呢? 多态是个很好的特性,但是动态绑定比较慢,因为要查虚函数表。而使用 crtp,完全消除了动态绑定,降低了继承带来的虚函数表查询开销。 好了,这篇只是对crtp的一个介绍,下次写写我们如何有效的使用crtp。 WebJun 9, 2024 · The “Curiously recurring template pattern” is a clever way to achieve what we want to achieve in this post, but it’s not the only way, and perhaps not the nicest way either.

WebMay 22, 2024 · And to hide the ugly static_cast and to make the word “CRTP” appear in the interface, we can use the crtp helper: template struct A : crtp { void bigAndSlow () const { return this->underlying ().helperfunction1 (); } }; And this code also ends up calling helperFunction1 in B.
