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!"");
