you want if you want to deal with ownership.
I think that can be solved by wrapping the resource in a struct
that deals with passing the ownership. Here is the one I am using
right now:
[code]
struct ResourceHandle(T, alias Deleter, T Default = T.init)
{
// Constructors/Destructor
this(in T handle) {m_handle = handle;}
@disable this(this);
~this() {Deleter(m_handle);}
// Operators
@disable void opAssign(ref ResourceHandle lvalue);
ref ResourceHandle opAssign(ResourceHandle rvalue)
{swap(m_handle, rvalue.m_handle); return this;}
// Methods
@property T handle() const {return m_handle;}
@property T handle(T handle) {Deleter(m_handle); m_handle =
handle; return m_handle;}
T release() {T result = m_handle; m_handle = Default; return
result;}
private:
T m_handle = Default;
}
[/code]
