Hi, Thanks both for your responses.
I didn't know that I could treat result as a normal variable. The template :=
will also be very helpful for me.
The porblem remains when using containers like double queue where the
implementation will make copies. For this reason, I tried to play with the
assignement operator, however, when implementing the operator, I obtain a
runtime error:
ype
container[T] = object
val: seq[T]
proc `=`[T](d: var container[T], s: container[T]) =
echo "= container called"
echo s
echo d
shallowCopy(d.val, s.val)
var c = container[int](val: @[1, 2, 3])
which outputs:
= container called
(val: @[1, 2, 3])
(val: nil)
Traceback (most recent call last)
main2.nim(11) main2
main2.nim(9) =
gc.nim(287) unsureAsgnRef
gc.nim(196) incRef
SIGSEGV: Illegal storage access. (Attempt to read from nil?)
Any idea how can I solve this error ?
