Hello community,
Is it possible to accomplish the following using ref instead of
pointers? If so, please share an example.
A ref cannot be a member of a type. But ref can be returned by a function.
So what you want is a *property* function:
```d
struct Engine
{
private const(DataSource)* _dataSourceStorage;
this(ref const(DataSource) dataSource)
{
this._dataSourceStorage = &dataSource;
}
@property ref dataSource() => *_dataSourceStorage;
... // rest the same
}
...
void main()
{
auto myData = DataSource([10, 20, 30]);
auto myEngine = Engine(myData); // initialize via ref
...
}
```

This is perfect. Thanks Steve. I had all but given up on this.
