What auto&& means--Jonathan Boccara

A refresher.

What auto&& means

by Jonathan Boccara

From the article:

Since C++11, we have a && in the language, and it can take some time to understand its meaning and all the consequences this can have on your code.

We’ve been through a detailed explanation of lvalues, rvalues and their references, which covers a lot of ground on this topic.

But there is one aspect that we have to talk about: what does auto&&, X&&, or even int&& means in code...

C++ coroutines: What happens if an exception occurs in my return_value?--Raymond Chen

C++ coroutines: What happens if an exception occurs in my return_value?

by Raymond Chen

From the article:

When I introduced a basic implementation of a promise type, I noted that the return_value method or return_void method is called when the coroutine performs a co_return. But what happens if the return_value or return_void method raises an exception?

C++ coroutines: Basic implementation of a promise type

by Raymond Chen

From the article:

Last time, we diagrammed out how the pieces of a coroutine fit together. Today we’ll fill in the diagram with code.

Fortunately, most of the hard work has already been done for us by the result_holder class we already wrote. We just need to adapt it to the format required by the coroutine specification...

Taming the power of C++ with AI

by Jens Weller

From the article:

In January Bryce Adelstein Lelbach gave a talk about NDVIDIAS CUDASTL fork at my online C++ User Group. Shortly after this talk was published on YouTube I got contacted by a start up, seeking feedback on their ideas of accelerating C++ with help of GPUs and AI...

Creating a task completion source for a C++ coroutine 4--Raymond Chen

Creating a task completion source for a C++ coroutine: Failing to produce a result

by Raymond Chen

From the article:

So far, we’ve been working on building a result_holder that can hold any type of result. But what about errors?

Because maybe you have code that’s waiting for a result, and the code that’s supposed to produce the result realizes that it messed up and wants to say, “Sorry, no result today.”...
