Struct `Values`

struct Values<T> { ... }

Iterate over multiple values for an argument via ArgMatches::remove_many.

Examples

# use clap_builder as clap;
# use clap::{Command, Arg, ArgAction};
let mut m = Command::new("myapp")
    .arg(Arg::new("output")
        .short('o')
        .action(ArgAction::Append))
    .get_matches_from(vec!["myapp", "-o", "val1", "-o", "val2"]);

let mut values = m.remove_many::<String>("output")
    .unwrap();

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