Alias `std.traits.FieldNameTuple`

Get as an expression tuple the names of the fields of a struct, class, or union. This consists of the fields that take up memory space, excluding the hidden fields like the virtual function table pointer or a context pointer for nested types. Inherited fields (for classes) are not included. If T isn't a struct, class, interface or union, an expression tuple with an empty string is returned.


						
				alias FieldNameTuple(T)
				 = staticMap!(NameOf,T.tupleof[0..__dollar-isNested!T]);

History

- Returned AliasSeq!"" for interfaces prior to 2.097

Example

import std.meta : AliasSeq;
struct S { int x; float y; }
static assert(FieldNameTuple!S == AliasSeq!("x", "y"));
static assert(FieldNameTuple!int == AliasSeq!"");
