FilterMembersOf

Filters all the members of a type based on a provided predicate

The predicate takes two parameters - the first is the type, the second is the string name of the member being iterated on.

template FilterMembersOf (

alias Fn

) {

import std.meta : Filter, ApplyLeft;;

alias ResolvedType = ResolvePointer!T;

alias FilterMembersOf = Filter!(ApplyLeft!(Fn, ResolvedType), __traits(allMembers, ResolvedType));

}
