Alias std.traits.hasElaborateDestructor

True if S or any type directly embedded in the representation of S defines an elaborate destructor. Elaborate destructors are introduced by defining ~this() for a struct.

alias hasElaborateDestructor(S) = hasElabDest!S;

Classes and unions never have elaborate destructors, even though classes may define ~this().


static assert(!hasElaborateDestructor!int);

static struct S1 { }
static struct S2 { ~this() {} }
static struct S3 { S2 field; }
static struct S4 { S3[1] field; }
static struct S5 { S3[] field; }
static struct S6 { S3[0] field; }
static struct S7 { @disable this(); S3 field; }
static assert(!hasElaborateDestructor!S1);
static assert( hasElaborateDestructor!S2);
static assert( hasElaborateDestructor!(immutable S2));
static assert( hasElaborateDestructor!S3);
static assert( hasElaborateDestructor!(S3[1]));
static assert(!hasElaborateDestructor!(S3[0]));
static assert( hasElaborateDestructor!S4);
static assert(!hasElaborateDestructor!S5);
static assert(!hasElaborateDestructor!S6);
static assert( hasElaborateDestructor!S7);
