How to get u8 values using clap

help

Hi, this is probably very trivial. I'm trying to get u8 values from cli using clap. All I managed to do so far is get &str. Could someone please help me figure this out.
Thanks,

you need to manually parse it.

If you want more simplified CLI argument parser declaration then use structopt

Thanks. StructOpt looks amazing. Will try that.
