The series continues.

Your own error condition

by Andrzej Krzemieński

From the article:

In the previous post we have seen how you can create your own error-code enumeration for representing different reasons for failure in your component, and how you can store them and convey them type erased via std::error_code. In this post we will see how you can inspect an error situation encoded in std::error_code, and how you can build useful queries about error conditions.

C++17 Features And STL Fixes In VS 2017 15.3--Stephan T. Lavavej

C++17 Features And STL Fixes In VS 2017 15.3

by Stephan T. Lavavej

From the article:

Visual Studio 2017’s first toolset update, version 15.3, is currently in preview and will be released in its final form very soon. (The toolset consists of the compiler, linker, and libraries. After VS 2017 RTM, the 15.1 and 15.2 updates improved the IDE. The 15.3 update improves both the IDE and the toolset. In general, you should expect the IDE to be updated at a higher frequency than the toolset.)

Video: C++ Concepts TS and Request for Input -- everythingcpp

By rwdougla | Aug 15, 2017 07:09 AM | Tags: c++20

This video teaches the Concepts syntax and motivation, with a request for viewers to try it out for themselves, to submit back their usage, to help guide a paper for the upcoming Albuquerque meeting.

C++ Concepts Intro: Need Your Input

by everythingcpp

From the article:

C++20 is slated to add most of the contents of the Concepts Technical Specification. Concerns about teach/learn-ability and usage preferences has kept some features from going in. This video covers introductory material on Concepts in C++ as it is in the technical specification. Afterward, I would like to hear from you!

CppCon 2016: A modern database interface for C++--Erik Smith

By Adrien Hamelin | Aug 14, 2017 02:44 PM | Tags: community

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

A modern database interface for C++

by Erik Smith

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ has historically had many options for database connectivity but has lacked a standard interface that other languages, such as Java, have had for a long time. This talk will present a standards grade interface along with experience with a reference implementation that includes support for at least 6 databases. A key aspect of the design is to show how modern C++ features can be used to achieve a high degree of both efficiency and ease-of-use. Specific features to be covered will include type conversion, connection pooling, I/O binding for scalars and arrays, row sets, direct/polymorphic interfaces, policy based design, the driver interface, and details on the implementation. Forward looking standards proposals, such as ranges and variants, will also be included in the discussion.
