Hey !
Thanks you for the quick answers !
As @solo989, just returning var Child like in the snippets below does not work
has it triggers a compile error.
proc set_value*(self: var Child, value: int): var Child {.discardable.} =
self.value = value
return self
proc get_child*(self: var Parent): var Child {.discardable.} =
var child = Child()
self.child = child
return child
# Raises:
# Error: 'child' escapes its stack frame; context: 'child'; see
https://nim-lang.org/docs/var_t_return.html
Run
Finally, @mratsim solutions works fine and make perfect sens :)
