Say I have type and a function look like this:
class Foo
{
void* data;
Foo clone ()
{
auto c = new Foo;
c.data = data;
return c;
}
}
void bar (Foo foo)
{
auto c = foo.clone();
...
}
Since I'm not changing anything on "foo" I thought that it could be a
good idea to declare it as const.
void bar (const Foo foo)
{
auto c = foo.clone();
...
}
In this case I also have to make "clone" const as well. Which is fine
sine "clone" doesn't change any of the fields.
class Foo
{
void* data;
Foo clone () const
{
auto c = new Foo;
c.data = data;
return c;
}
}
But now when I compile this code I get this error:
Error: cannot implicitly convert expression (this.data) of type
const(void*) to void*
Any idea how to solve this? Or would I need to drop const.
