Enum member std.traits.isIntegral
Detect whether T
is a built-in integral type. Types bool
,
char
, wchar
, and dchar
are not considered integral.
enum isIntegral(T)
= false;
Example
static assert(
isIntegral!byte &&
isIntegral!short &&
isIntegral!int &&
isIntegral!long &&
isIntegral!(const(long)) &&
isIntegral!(immutable(long))
);
static assert(
!isIntegral!bool &&
!isIntegral!char &&
!isIntegral!double
);
// types which act as integral values do not pass
struct S
{
int val;
alias val this;
}
static assert(!isIntegral!S);
