Function `std.traits.rvalueOf`

Creates an lvalue or rvalue of type T for typeof(...) and traits(compiles, ...) purposes. No actual value is returned.


						
				{null} rvalueOf(T)
				();

Note

Trying to use returned value will result in a "Symbol Undefined" error at link time.

Example

// Note that `f` doesn't have to be implemented
// as is isn't called.
int f(int);
bool f(ref int);
static assert(is(typeof(f(rvalueOf!int)) == int));
static assert(is(typeof(f(lvalueOf!int)) == bool));

int i = rvalueOf!int; // error, no actual value is returned
