Function std.range.primitives.moveFront
Moves the front of rr.front in a
destroyable state that does not allocate any resources (usually equal
to its .init value).
Prototype
ElementType!R moveFront(R)( R r );
Example
auto a = [ 1, 2, 3 ];
assert(moveFront(a) == 1);
// define a perfunctory input range
struct InputRange
{
@property bool empty() { return false; }
@property int front() { return 42; }
void popFront() {}
int moveFront() { return 43; }
}
InputRange r;
assert(moveFront(r) == 43);
