Macro clap::values_t [−][src]
Convenience macro getting a typed value Vec<T>
where T
implements std::str::FromStr
This macro returns a clap::Result<Vec<T>>
which allows you as the developer to decide
what you’d like to do on a failed parse.
Examples
let matches = App::new("myapp") .arg_from_usage("[seq]... 'A sequence of pos whole nums, i.e. 20 45'") .get_matches(); let vals = values_t!(matches.values_of("seq"), u32).unwrap_or_else(|e| e.exit()); for v in &vals { println!("{} + 2: {}", v, v + 2); } let vals = values_t!(matches, "seq", u32).unwrap_or_else(|e| e.exit()); for v in &vals { println!("{} + 2: {}", v, v + 2); }
