How to Construct C++ Objects Without Making Copies by Miguel Raggi
From the article:
C++ references are a powerful but tricky tool: used correctly, they can improve performance with little impact on the clarity of code. But used badly, they can hide performance issues, or even send a peaceful program into the realm of undefined behaviour. In this post, we will explore how to use the various references of C++ to minimize copies when constructing an object that holds a value, and how in some cases we can even reach zero copies. This article assumes that you’re familiar with move semantics, lvalue, rvalue and forwarding references. If you’d like to be refreshed on the subject, you can take a look at lvalues, rvalues and their (...)

After reading the series of posts on the CRTP, Fluent C++ reader Miguel Raggi reached out to me with the following email (reproduced with his permission): Dear Jonathan Boccara, […] After reading the posts on the curiously recurring template pattern, I’m wondering how to (expressively) implement this with 3 or more classes. Say, you have 3 […]
