Function map_to_slice 

pub fn map_to_slice<K, V, R, F>(map: &HashMap<K, V>, iteratee: F) -> Vec<R>
where
    K: Eq + Hash,
    F: Fn(&K, &V) -> R,

Transforms the entries of a map into a slice using a provided function.

Arguments

• map - The input map whose entries are to be transformed.
• iteratee - A function that takes a reference to a key and its value, returning a new value.

Returns

• Vec<R> - A vector containing the transformed values.

Examples

use lowdash::map_to_slice;
use std::collections::HashMap;

let mut map = HashMap::new();
map.insert("a", 1);
map.insert("b", 2);

let transformed = map_to_slice(&map, |k, v| format!("{}:{}", k, v));
assert!(transformed.contains(&"a:1".to_string()));
assert!(transformed.contains(&"b:2".to_string()));
