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) = __traits(isIntegral, T) && is(IntegralTypeOf!T);

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);
