Enum member std.traits.classInstanceAlignment

Returns class instance alignment.

enum classInstanceAlignment(T) = __traits(classInstanceAlignment, T);

Example

class A { byte b; }
class B { long l; }

// As class instance always has a hidden pointer
static assert(classInstanceAlignment!A == (void*).alignof);
static assert(classInstanceAlignment!B == long.alignof);
