Template std.traits.RepresentationTypeTuple
Get the primitive types of the fields of a struct or class, in topological order.
Arguments
template RepresentationTypeTuple(T);
Example
struct S1 { int a; float b; }
struct S2 { char[] a; union { S1 b; S1 * c; } }
alias R = RepresentationTypeTuple!S2;
assert(R.length == 4
&& is(R[0] == char[]) && is(R[1] == int)
&& is(R[2] == float) && is(R[3] == S1*));
Example
// simple types
static assert(!hasRawAliasing!int);
static assert( hasRawAliasing!(char*));
// references aren't raw pointers
static assert(!hasRawAliasing!Object);
// built-in arrays do contain raw pointers
static assert( hasRawAliasing!(int[]));
// aggregate of simple types
struct S1 { int a; double b; }
static assert(!hasRawAliasing!S1);
// indirect aggregation
struct S2 { S1 a; double b; }
static assert(!hasRawAliasing!S2);
Example
// simple types
static assert(!hasRawUnsharedAliasing!int);
static assert( hasRawUnsharedAliasing!(char*));
static assert(!hasRawUnsharedAliasing!(shared char*));
// references aren't raw pointers
static assert(!hasRawUnsharedAliasing!Object);
// built-in arrays do contain raw pointers
static assert( hasRawUnsharedAliasing!(int[]));
static assert(!hasRawUnsharedAliasing!(shared int[]));
// aggregate of simple types
struct S1 { int a; double b; }
static assert(!hasRawUnsharedAliasing!S1);
// indirect aggregation
struct S2 { S1 a; double b; }
static assert(!hasRawUnsharedAliasing!S2);
// struct with a pointer member
struct S3 { int a; double * b; }
static assert( hasRawUnsharedAliasing!S3);
struct S4 { int a; shared double * b; }
static assert(!hasRawUnsharedAliasing!S4);
