Agreed, though I'm assuming I have to use `ptr` for C types.
By the way, is following code contain a bug? I was trying to see if `: var
Thingy` return type returns a reference (or a pointer) but it doesn't seem to
do that:
type
Thingy = object
x*: int
OwnsThingy = object
t*: ptr Thingy
proc makeOwnsThingy(): OwnsThingy =
result.t = cast[ptr Thingy](alloc(Thingy.sizeof))
result.t.x = 100
proc getInner(self: OwnsThingy): var Thingy = self.t[]
proc inc(self: var Thingy) = self.x += 1
when isMainModule:
let ot = makeOwnsThingy()
var thing = getInner(ot)
echo ot.t[] # Prints 100
thing.inc()
echo ot.t[] # Prints 100 again, should have printed 101, right?
Run
