I was looking through the standard library for a good way to split a range into several ranges based on value changes in the stream: AAABB would be split on the AB transition into: AAA BB I just couldn't figure out an elegant way to do it? Any ideas?

equivalent of typeid(Class).name at compile-time

2019-11-21 Thread Steven Schveighoffer via Digitalmars-d-learn
I thought I could do typeid(Class).name to get the class name that will be returned at runtime if you did typeid(instance).name. But it's not accessible at compile-time. What compile-time string should I use for instance in a constructed switch statement? I'm trying to implement serialization
