Struct `Indices`

struct Indices<'a> { ... }

Iterate over indices for where an argument appeared when parsing, via ArgMatches::indices_of

Examples

# use clap_builder as clap;
# use clap::{Command, Arg, ArgAction};
let m = Command::new("myapp")
    .arg(Arg::new("output")
        .short('o')
        .num_args(1..)
        .action(ArgAction::Set))
    .get_matches_from(vec!["myapp", "-o", "val1", "val2"]);

let mut indices = m.indices_of("output").unwrap();

assert_eq!(indices.next(), Some(2));
assert_eq!(indices.next(), Some(3));
assert_eq!(indices.next(), None);
