Don’t Make Your Interfaces *Deceptively* Simple--Jonathan Boccara

A good thing to think about.

Don’t Make Your Interfaces *Deceptively* Simple

by Jonathan Boccara

From the article:

Just because we can provide an interface doesn’t mean that we should.

At least this is one of the takeaways that I got from from Howard Hinnant’s opening keynote at Meeting C++ 2019.

In this impressive keynote, Howard made a presentation about <chrono> and the host of features it brings in C++20. But beyond showing us how to use <chrono>, Howard explained some of the design rationale of this library.

Those are precious lessons of design, especially coming from someone who had a substantial impact on the design of the standard library. I believe we can apply those practices to our own code when designing interfaces.

So, just because we can provide an interface doesn’t mean that we should. To illustrate what this means in practice, let’s go over two examples in the C++ standard library...

So many possibilities!

C++ coroutines: Getting started with awaitable objects

by Raymond Chen

From the article:

Coroutines were added to C++20, and Lewis Baker has a nice introduction to them.

  • Coroutine theory.
  • Understanding operator co_await.
  • Understanding the promise type.

But I’m going to write another one, taking a more practical approach: The least you need to know to accomplish various coroutine tasks...

C++20: Concepts, the Details

by Rainer Grimm

From the article:

In my last post C++20: Two Extremes and the Rescue with Concepts, I gave the first motivation for concepts. Concepts put semantic constraints on template parameters. Today, I present different use-cases for concepts in a compact form...
