[][src]Struct clap::Values

pub struct Values<'a> { /* fields omitted */ }

An iterator for getting multiple values out of an argument via the ArgMatches::values_of method.


let m = App::new("myapp")
    .get_matches_from(vec!["myapp", "-o", "val1", "val2"]);

let mut values = m.values_of("output").unwrap();

assert_eq!(values.next(), Some("val1"));
assert_eq!(values.next(), Some("val2"));
assert_eq!(values.next(), None);
