Enum member std.traits.hasUnsharedAliasing
Returns true if and only if T's representation includes at
least one of the following:
- a raw pointer
U*andUis not immutable or shared; - an array
U[]andUis not immutable or shared; - a reference to a class type
CandCis not immutable or shared. - an associative array that is not immutable or shared.
- a delegate that is not shared.
enum hasUnsharedAliasing(T...) = anySatisfy!(hasUnsharedAliasingImpl, T);
Example
struct S1 { int a; Object b; }
struct S2 { string a; }
struct S3 { int a; immutable Object b; }
static assert( hasUnsharedAliasing!S1);
static assert(!hasUnsharedAliasing!S2);
static assert(!hasUnsharedAliasing!S3);
struct S4 { int a; shared Object b; }
struct S5 { char[] a; }
struct S6 { shared char[] b; }
struct S7 { float[3] vals; }
static assert(!hasUnsharedAliasing!S4);
static assert( hasUnsharedAliasing!S5);
static assert(!hasUnsharedAliasing!S6);
static assert(!hasUnsharedAliasing!S7);
