Andrei Alexandrescu (born 1969) is a Romanian-American C++ and D language programmer and author. He is particularly known for his pioneering work on policy-based design implemented via template metaprogramming. These ideas are articulated in his book Modern C++ Design and were first implemented in his programming library, Loki. He also implemented the "move constructors" concept in his MOJO library. He contributed to the C/C++ Users Journal under the byline "Generic". Alexandrescu worked as a research scientist at Facebook, before departing the company in August 2015 in order to focus on developing the D programming language.

More recently, he has been assisting Walter Bright in the development of the D programming language. Alexandrescu released a book titled The D Programming Language in May 2010.

Alexandrescu, Herb Sutter, and Scott Meyers run C++ and Beyond, a small annual technical conference.

Contributions

Expected is a template class for C++ which has been proposed for inclusion in Boost. Alexandrescu proposes Expected as a class for use as a return value which contains either a T or the exception preventing its creation, which is an improvement over use of either return codes or exceptions exclusively. Expected can be thought of as a restriction of sum (union) types or algebraic datatypes in various languages, e.g., Hope, or the more recent Haskell and Gallina; or of the error handling mechanism of Google's Go, or the Result type in Rust.

He explains the benefits of Expected<T> as:

Associates errors with computational goals

Naturally allows multiple exceptions in flight

Switch between error handling and exception throwing styles

Teleportation possible across thread boundaries, across nothrow subsystem boundaries and across time (save now, throw later)

Collect, group, combine exceptions

Example

For example, instead of any of the following common function prototypes:

int parseInt(const string&); // Returns 0 on error and sets errno.

int parseInt(const string&); // Throws invalid_input or overflow

he proposes the following:

Expected<int> parseInt(const string&); // Returns an expected int: either an int or an exception
