Is there a way to implement filterMap (meaning do mapping of a

It's probably not a good idea to do this in general. Expecting
a lot of exceptions handling happening during normal program
execution (if you want to filter out roughly half of the input
array) will result in a major performance loss. Exceptions are
best left to just do error handling on a very rarely used code
path for troubleshooting purposes.
Thanks for the feedback.
This might be true, but in my example I would parse the input
always with conv.to, so I would need to handle the exception(s).
The "original"
https://doc.rust-lang.org/std/iter/trait.Iterator.html#method.filter_map works with the Option(Some/None) ...
Kind regards,
