What is the difference of the following code snippets?
The following one is modelled after the standard _newException_ proc
MyError= object of CatchableError
count:int
...
proc newMyError(ct:int) : owned(ref MyError ) {.noinline.} =
var e: owned(ref MyError)
new(e)
e.count= ct
return e
...
try :
raise newMyError(3)
except MyError as E :
echo "caught", E.count
Run
Is the following alternative safe, as well?
MyError= ref object of CatchableError
count:int
...
try :
raise MyError(count:3)
except MyError as E :
echo "caught ", E.count
Run
