Re: turning an array of structs into a struct of arrays

I can use FieldTypeTuple and FieldNameTuple, but I am a bit lost as to how without static foreach to loop through these in order to generate a mixin to declare the new type. I can turn it into a string, but what is the better option? The simplest solution is something like: template

Re: turning an array of structs into a struct of arrays

Not necessarily the best solution to the problem, but I just wanted to show this because I think it's kinda cool: https://gist.github.com/John-Colvin/103d3c064ad6cb4cf435#file-transformmembers-d Very impressive - now I have to try to understand how it works...!

turning an array of structs into a struct of arrays

I have an array of structs eg struct PriceBar { DateTime date; double open; double high; double low; double close; } (which fields are present in this particular struct will depend on template arguments). what is the best way to turn these at compile time into a struct of arrays?
