Function vit_servicing_station_lib::utils::collections::dedup_by_key_keep_last

pub fn dedup_by_key_keep_last<F, I, K>(iter: I, key_fn: F) -> Vec<I::Item>where
    I: Iterator,
    F: Fn(&I::Item) -> K,
    K: Eq + Hash,

Removes all but the last occurrence of elements that resolve to the same key maintaining the order in which they where first found.

Examples

use vit_servicing_station_lib::utils::collections::dedup_by_key_keep_last;

let v = vec![(0, "a"), (0, "b"), (1, "c"), (1, "d"), (2, "e")];

assert_eq!(dedup_by_key_keep_last(v.into_iter(), |i| i.0), [(0, "b"), (1, "d"), (2, "e")]);
