Sounds like Google/abseil's "StatusOr', but maybe a bit more freefrom? https://abseil.io/docs/cpp/guides/status https://abseil.io/docs/cpp/guides/status

- loeg 4y agoYeah, we use a fixed-E alias of folly::Expected<> in our codebase which is similar to absl::StatusOr. Something like: namespace our_project { class Status { ... }; template <class T> using Expected = folly::Expected<T, Status>; } absl::StatusOr<T> looks a lot like our_project::Expected<T>. This pattern of providing your own error type and aliasing Result is also somewhat common in Rust, I believe.
