Alias std.traits.Fields
Get as a tuple the types 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.
If T
isn't a struct, class, interface or union returns a tuple
with one element T
.
alias Fields(T)
= typeof(T .tupleof[0..__dollar-isNested!T]);
History
- Returned AliasSeq!(Interface)
for interfaces prior to 2.097
Example
import std .meta : AliasSeq;
struct S { int x; float y; }
static assert(is(Fields!S == AliasSeq!(int, float)));
