The Dawn of a New Error with Phil Nash

21 января мы соберемся в уютном офисе компании JetBrains, чтобы поговорить об обработке ошибок в C++. Phil Nash представит новый доклад, который является логическим продолжением предыдущего его выступления на митапе нашего сообщества. Приходите, узнавайте новое, задавайте вопросы, предлагайте альтернативы, дискутируйте!

Доклад будет представлен на английском языке.

The Dawn of a New Error, Phil Nash

Abstract: As a community we've tried many different ways to express, propagate and handle error conditions in our code over the years. Each seem to have different trade-offs, with none being perfect in all cases.

This presentation is the follow-up to my earlier talk, "Option(al) Is Not a Failure", where I surveyed existing error-handling approaches and score them against each other, leading up to the new proposal, p0709, "Zero-overhead deterministic exceptions".

We'll summarise some of that background so we're all on the same page, but in this talk we're going to dig into the proposal in more depth - and look at the supporting proposals, p1028 (std::error) and p1029 ([[move relocates]]) and others. We'll also comment similar mechanisms in other languages, notably Swift, to get an idea of how it might work out in practice.
