Expand description

Creates an iterator which gives the current opt’s number as well as the option.

The iterator returned yields pairs (i, val), where i is the OptNumber and val is the Opt returned by the iterator.

Required methods

Creates an iterator which gives the current Opt along with its Number.

use kwap_msg::alloc::*;

let opt_a = Opt { delta: OptDelta(12),
                  value: OptValue(Vec::new()) };
let opt_b = Opt { delta: OptDelta(2),
                  value: OptValue(Vec::new()) };
let opts = vec![opt_a.clone(), opt_b.clone()];

let opt_ns = opts.into_iter().enumerate_option_numbers().collect::<Vec<_>>();

assert_eq!(opt_ns, vec![(OptNumber(12), opt_a), (OptNumber(14), opt_b)])
