August 16, 2018 C++ Expected converted to idiomatic D | ||||
---|---|---|---|---|
| ||||
In https://www.youtube.com/watch?v=nVzgkepAg5Y Andrei describes his proposal for STL `Expected` planned to be included in C++20. Have anybody converted the C++ proposal to idiomatic D, yet? Hopefully without the pointer-legacy which unfortunately was allowed into `std:optional`. Andrei claims we should it as return types for non-throwing variants of parse() and to() in the works at https://github.com/dlang/phobos/pull/6665 |

I get the feeling from the talk that Andrei has some opinions about how it should be done that aren't completely in line with what has been proposed for the C++ standard.

Anyhow my implementation at https://github.com/nordlow/phobos-next/blob/master/src/expected.d should match his C++ code in the lecture, AFAICT. My code doesn't depend on other modules an compiles very fast (~46 ms in my machine) (with DMD -debug -unittest). |
